1、整体实现的效果图

2、项目结构图

这上面项目结构图也是一目了然，有什么功能展示。大家也看到了，这上面类有点多，如果全部贴出来，不大可能，有兴趣下载本文源码。

3、看看基础类BaseActivity

我就贴一下基础类，还有实现类。因为这些一段段代码易于其他项目使用。

package com.org.base;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import com.example.activity.R;
import com.example.activity.R.layout;
import com.org.dialog.LoadingDialog;
import com.org.view.HandyTextView;

import android.os.AsyncTask;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Toast;
import android.app.Activity;
import android.content.Intent;

public class BaseActivity extends Activity {
protected LoadingDialog mLoadingDialog;
/**
* 屏幕的宽度、高度、密度
*/
protected int mScreenWidth;
protected int mScreenHeight;
protected float mDensity;
//异步加载任务的list
protected List<AsyncTask<Void, Void, Boolean>> mAsyncTasks = new ArrayList<AsyncTask<Void, Void, Boolean>>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mLoadingDialog = new LoadingDialog(this, "请求提交中");
DisplayMetrics metric = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metric);
mScreenWidth = metric.widthPixels;
mScreenHeight = metric.heightPixels;
mDensity = metric.density;
}

protected void putAsyncTask(AsyncTask<Void, Void, Boolean> asyncTask) {
mAsyncTasks.add(asyncTask.execute());
}

protected void clearAsyncTask() {
Iterator<AsyncTask<Void, Void, Boolean>> iterator = mAsyncTasks
.iterator();
while (iterator.hasNext()) {
AsyncTask<Void, Void, Boolean> asyncTask = iterator.next();
if (asyncTask != null && !asyncTask.isCancelled()) {
asyncTask.cancel(true);
}
}
mAsyncTasks.clear();
}

protected void showLoadingDialog(String text) {
if (text != null) {
mLoadingDialog.setText(text);
}
mLoadingDialog.show();
}

protected void dismissLoadingDialog() {
if (mLoadingDialog.isShowing()) {
mLoadingDialog.dismiss();
}
}

/** 短暂显示Toast提示(来自res) **/
protected void showShortToast(int resId) {
Toast.makeText(this, getString(resId), Toast.LENGTH_SHORT).show();
}

/** 短暂显示Toast提示(来自String) **/
protected void showShortToast(String text) {
Toast.makeText(this, text, Toast.LENGTH_SHORT).show();
}

/** 长时间显示Toast提示(来自res) **/
protected void showLongToast(int resId) {
Toast.makeText(this, getString(resId), Toast.LENGTH_LONG).show();
}

/** 长时间显示Toast提示(来自String) **/

Toast.makeText(this, text, Toast.LENGTH_LONG).show();
}

/** 显示自定义Toast提示(来自res) **/
protected void showCustomToast(int resId) {
View toastRoot = LayoutInflater.from(BaseActivity.this).inflate(
R.layout.common_toast, null);
((HandyTextView) toastRoot.findViewById(R.id.toast_text))
.setText(getString(resId));
Toast toast = new Toast(BaseActivity.this);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setView(toastRoot);
toast.show();
}

/** 显示自定义Toast提示(来自String) **/
protected void showCustomToast(String text) {
View toastRoot = LayoutInflater.from(BaseActivity.this).inflate(
R.layout.common_toast, null);
((HandyTextView) toastRoot.findViewById(R.id.toast_text)).setText(text);
Toast toast = new Toast(BaseActivity.this);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setView(toastRoot);
toast.show();
}

/** Debug输出Log日志 **/
protected void showLogDebug(String tag, String msg) {
Log.d(tag, msg);
}

/** Error输出Log日志 **/
protected void showLogError(String tag, String msg) {
Log.e(tag, msg);
}

/** 通过Class跳转界面 **/
protected void startActivity(Class<?> cls) {
startActivity(cls, null);
}

/** 含有Bundle通过Class跳转界面 **/
protected void startActivity(Class<?> cls, Bundle bundle) {
Intent intent = new Intent();
intent.setClass(this, cls);
if (bundle != null) {
intent.putExtras(bundle);
}
startActivity(intent);
}

/** 默认退出 **/
protected void defaultFinish() {
super.finish();
}
}

4、BasePopupWindow

package com.org.base;

import android.annotation.TargetApi;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.os.Build;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.View;
import android.widget.PopupWindow;

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public abstract class BasePopupWindow extends PopupWindow {

protected View mContentView;
protected onSubmitClickListener mOnSubmitClickListener;

public BasePopupWindow() {
super();
}

public BasePopupWindow(Context context, AttributeSet attrs,
int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}

public BasePopupWindow(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

public BasePopupWindow(Context context, AttributeSet attrs) {
super(context, attrs);
}

public BasePopupWindow(Context context) {
super(context);
}

public BasePopupWindow(int width, int height) {
super(width, height);
}

public BasePopupWindow(View contentView, int width, int height,
boolean focusable) {
super(contentView, width, height, focusable);
}

public BasePopupWindow(View contentView) {
super(contentView);
}

@SuppressWarnings("deprecation")
public BasePopupWindow(View contentView, int width, int height) {
super(contentView, width, height, true);
mContentView = contentView;
setBackgroundDrawable(new BitmapDrawable());
initViews();
initEvents();
init();
}

public abstract void initViews();

public abstract void initEvents();

public abstract void init();

public View findViewById(int id) {
return mContentView.findViewById(id);
}

/**
* 显示在parent的上部并水平居中
*
* @param parent
*/
public void showViewTopCenter(View parent) {
showAtLocation(parent, Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);
}

/**
* 显示在parent的中心
*
* @param parent
*/
public void showViewCenter(View parent) {
showAtLocation(parent, Gravity.CENTER, 0, 0);
}

/**
* 添加确认单击监听
*
* @param l
*/
public void setOnSubmitClickListener(onSubmitClickListener l) {
mOnSubmitClickListener = l;
}

public interface onSubmitClickListener {
void onClick();
}

}

5、BaseArrayListAdapter

package com.org.base;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

//基本的适配器
public class BaseArrayListAdapter extends BaseAdapter {

protected Context mContext;
protected LayoutInflater mInflater;
protected List<String> mDatas = new ArrayList<String>();

//String数组添加数据源
public BaseArrayListAdapter(Context context, String... datas) {
mContext = context;
mInflater = LayoutInflater.from(context);
if (datas != null && datas.length > 0) {
mDatas = Arrays.asList(datas);
}
}

//用list方式添加数据源
public BaseArrayListAdapter(Context context, List<String> datas) {
mContext = context;
mInflater = LayoutInflater.from(context);
if (datas != null && datas.size() > 0) {
mDatas = datas;
}
}

@Override
public int getCount() {
return mDatas.size();
}

@Override
public Object getItem(int position) {
return mDatas.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
return null;
}
}

6、实现自定义对话框，进度条以及popup弹出框，主MainActivity

package com.example.activity;

import com.org.base.BaseActivity;
import com.org.dialog.EditTextDialog;
import com.org.dialog.SimpleListDialog;
import com.org.dialog.SimpleListDialog.onSimpleListItemClickListener;
import com.org.popupwindow.ChatPopupWindow;
import com.org.popupwindow.ChatPopupWindow.onChatPopupItemClickListener;
import com.viw.adapt.CheckListDialogAdapter;

import android.R.layout;
import android.content.DialogInterface;
import android.os.Bundle;
import android.os.Handler;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.RelativeLayout;

public class MainActivity extends BaseActivity
implements
OnClickListener,
onChatPopupItemClickListener{

protected SimpleListDialog mDialog;
private int mCheckId = 0;
private ChatPopupWindow mChatPopupWindow;
private int mWidth;
private int mHeaderHeight;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

findViewById(R.id.button1).setOnClickListener(this);
findViewById(R.id.button2).setOnClickListener(this);
findViewById(R.id.button3).setOnClickListener(this);
findViewById(R.id.button4).setOnClickListener(this);
findViewById(R.id.button5).setOnClickListener(this);
initPopupWindow();
}

public void onSimpleListItem() {
String[] modes = new String[]{"测试一","测试二","测试三"};
mDialog = new SimpleListDialog(this);
mDialog.setTitle("单选框");
mDialog.setTitleLineVisibility(View.GONE);
mDialog.setAdapter(new CheckListDialogAdapter(mCheckId, this, modes));
//用匿名内部类实现接口监听
mDialog.setOnSimpleListItemClickListener(new DialogItemClickListener());
mDialog.show();
}

protected class DialogItemClickListener implements
onSimpleListItemClickListener {

@Override
public void onItemClick(int position) {
mCheckId = position;
}
}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:

showLoadingDialog("正在加载。。。");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
dismissLoadingDialog();

}
}, 10000);
break;
case R.id.button2:
onSimpleListItem();
break;
case R.id.button3:
onEditTextDialog();
break;
case R.id.button4:
RelativeLayout layoutShow = (RelativeLayout)findViewById(R.id.layoutShow);
mChatPopupWindow.showAtLocation(layoutShow, Gravity.RIGHT
| Gravity.TOP, -10, mHeaderHeight + 10);
break;
case R.id.button5:
startActivity(PullRefreshListViewActivity.class);
break;
default:
break;
}

}

private void onEditTextDialog() {
final EditTextDialog mEditTextDialog = new EditTextDialog(this);
mEditTextDialog.setTitle("填写推荐人");
mEditTextDialog.setButton("取消",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
mEditTextDialog.cancel();
}
}, "确认", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
String text = mEditTextDialog.getText();
if (text == null) {
mEditTextDialog.requestFocus();
} else {
mEditTextDialog.dismiss();
}
}
});
mEditTextDialog.show();
}

//初始化PopupWindow
protected void initPopupWindow() {
mWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
130, getResources().getDisplayMetrics());
mHeaderHeight = (int) TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP, 48, getResources()
.getDisplayMetrics());
mChatPopupWindow = new ChatPopupWindow(this, mWidth,
LayoutParams.WRAP_CONTENT);
mChatPopupWindow.setOnChatPopupItemClickListener(this);
}

//以下是popupwindow的选择监听事件
@Override
public void onVoiceModeClick() {
showCustomToast("pop监听1");

}

@Override
public void onCreateClick() {
showCustomToast("pop监听2");
}

@Override
public void onSynchronousClick() {
showCustomToast("pop监听3");

}

}

7、下拉刷新PullRefreshListViewActivity

package com.example.activity;

import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import com.org.base.BaseActivity;
import com.org.view.PullRefreshListView;
import com.org.view.PullRefreshListView.OnCancelListener;
import com.org.view.PullRefreshListView.OnRefreshListener;
import com.viw.adapt.CheckListDialogAdapter;

public class PullRefreshListViewActivity extends BaseActivity
implements
OnRefreshListener,
OnCancelListener,
OnItemClickListener{
private PullRefreshListView mRefreshListView;
String[] modes = new String[]{"测试一","测试二","测试三"};
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_refresh);

initViews();
}

protected void initViews() {
mRefreshListView = (PullRefreshListView) findViewById(R.id.otherfeedlist_mmrlv_list);
//适配器我随便用了一个
mRefreshListView.setAdapter(new CheckListDialogAdapter(1, this, modes));
mRefreshListView.setOnItemClickListener(this);
mRefreshListView.setOnRefreshListener(this);
mRefreshListView.setOnCancelListener(this);
}

@Override
public void onCancel() {
//取消刷新
mRefreshListView.onRefreshComplete();
}

@Override
public void onRefresh() {

//异步加载线程
putAsyncTask(new AsyncTask<Void, Void, Boolean>() {
@Override
protected Boolean doInBackground(Void... params) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {

}
return null;
}

@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
//这里写刷新adapt数据就行可以了

mRefreshListView.onRefreshComplete();
}
});

}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// listview的单击事件就不写了

}
}
