(十）android项目中，通用布局的对话框的实现。

在工作中，我们的APP项目中经常需要用到dialog，一般设计师对于一个APP项目，会设计使用同一个风格，显示不同内容的对话框，所以为了提高开发的效率，我们可以针对一个项目设计一个通用的对话框，所有用到的地方都可以调用。本文针对下面效果的对话框，实现了一个通用对话框，具体实现核心代码如下所示。



1 CustomDialog.java代码实现如下所示：

import android.app.ActionBar.LayoutParams;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.CheckBox;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.RelativeLayout;
import android.widget.TextView;

/**

*/
public class CustomDialog extends Dialog {

private TextView custom_dialog_tv_title;
private TextView custom_dialog_tv_message;
private RelativeLayout custom_dialog_rl_tip;
private CheckBox custom_dialog_cb;
private TextView custom_dialog_tv_tip;
private TextView custom_dialog_tv_cancel;
private TextView custom_dialog_tv_confirm;

public CustomDialog(Context context, int theme) {
super(context, theme);
initView();
}

public CustomDialog(Context context) {
this(context, R.style.CustomDialog);
}

private void initView() {
setContentView(R.layout.custom_dialog);
custom_dialog_tv_title = (TextView) findViewById(R.id.custom_dialog_tv_title);
custom_dialog_tv_message = (TextView) findViewById(R.id.custom_dialog_tv_message);
custom_dialog_rl_tip = (RelativeLayout) findViewById(R.id.custom_dialog_rl_tip);
custom_dialog_cb = (CheckBox) findViewById(R.id.custom_dialog_cb);
custom_dialog_tv_tip = (TextView) findViewById(R.id.custom_dialog_tv_tip);
custom_dialog_tv_cancel = (TextView) findViewById(R.id.custom_dialog_tv_cancel);
custom_dialog_tv_confirm = (TextView) findViewById(R.id.custom_dialog_tv_confirm);
}

public void setDialogTitle(int visibility) {
custom_dialog_tv_title.setVisibility(visibility);
}

public void setDialogTitle(int visibility, String title) {
custom_dialog_tv_title.setVisibility(visibility);
if (visibility == View.VISIBLE) {
custom_dialog_tv_title.setText(title);
}
}

public void setDialogMessage(String message) {
custom_dialog_tv_message.setText(message);
}

public void setDialogTip(int visibility) {
custom_dialog_rl_tip.setVisibility(visibility);
}

public void setDialogTip(int visibility, String tip,
OnCheckedChangeListener listener) {
custom_dialog_rl_tip.setVisibility(visibility);
if (View.VISIBLE == visibility) {
custom_dialog_cb.setOnCheckedChangeListener(listener);
custom_dialog_tv_tip.setText(tip);
}
}

public void setCheckBox(boolean checked) {
custom_dialog_cb.setChecked(checked);
}

public boolean isDialogCheckBoxChecked() {
return custom_dialog_cb.isChecked();
}

public void setDialogCancel(int visibility) {
custom_dialog_tv_cancel.setVisibility(visibility);
}

public void setDialogCancel(int visibility, String text,
android.view.View.OnClickListener listener) {
custom_dialog_tv_cancel.setVisibility(visibility);
if (visibility == View.VISIBLE) {
custom_dialog_tv_cancel.setText(text);
custom_dialog_tv_cancel.setOnClickListener(listener);
}
}

public void setDialogConfirm(int visibility) {
custom_dialog_tv_confirm.setVisibility(visibility);
}

public void setDialogConfirm(int visibility, String text,
android.view.View.OnClickListener listener) {
custom_dialog_tv_confirm.setVisibility(visibility);
if (visibility == View.VISIBLE) {
custom_dialog_tv_confirm.setText(text);
custom_dialog_tv_confirm.setOnClickListener(listener);
}
}

@Override
public void show() {
// TODO Auto-generated method stub
super.show();
Window dialogWindow = this.getWindow();
dialogWindow.setGravity(Gravity.CENTER);
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
lp.width = LayoutParams.WRAP_CONTENT;
lp.height = LayoutParams.WRAP_CONTENT;
dialogWindow.setAttributes(lp);
}
}

2、custom_dialog.xml中的代码如下所示：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="@dimen/custom_dialog_rl_width"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/common_custom_dialog_bg"
android:paddingBottom="@dimen/custom_dialog_rl_padding_botton"
android:paddingLeft="@dimen/custom_dialog_rl_padding_left"
android:paddingRight="@dimen/custom_dialog_rl_padding_right" >

<TextView
android:id="@+id/custom_dialog_tv_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/custom_dialog_margin_top"
android:text="标题"
android:textColor="@color/custom_dialog_tv_color1"
android:textSize="@dimen/custom_dialog_tv_text_size1" />

<TextView
android:id="@+id/custom_dialog_tv_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/custom_dialog_tv_title"
android:layout_marginTop="@dimen/custom_dialog_margin_top"
android:text="内容，提示用户的信息"
android:textColor="@color/custom_dialog_tv_color2"
android:textSize="@dimen/custom_dialog_tv_text_size3" />

<RelativeLayout
android:id="@+id/custom_dialog_rl_tip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/custom_dialog_tv_message"
android:layout_marginTop="@dimen/custom_dialog_margin_top"
>

<CheckBox
android:id="@+id/custom_dialog_cb"
style="@style/CustomDialogCheckBoxTheme"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:checked="true" />

<TextView
android:id="@+id/custom_dialog_tv_tip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="8dp"
android:layout_toRightOf="@id/custom_dialog_cb"
android:text="下次不提示"
android:textColor="@color/custom_dialog_tv_color2"
android:textSize="@dimen/custom_dialog_tv_text_size2" />
</RelativeLayout>

<RelativeLayout
android:id="@+id/custom_dialog_rl_select"
android:layout_width="wrap_content"
android:layout_height="36dp"
android:layout_alignParentRight="true"
android:layout_below="@id/custom_dialog_rl_tip"
android:layout_marginTop="@dimen/custom_dialog_margin_top" >

<TextView
android:id="@+id/custom_dialog_tv_cancel"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="@drawable/common_custom_dialog_btn_selector"
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:text="确定"
android:textColor="@color/custom_dialog_text_bg_color_selector"
android:textSize="@dimen/custom_dialog_tv_text_size3" />

<TextView
android:id="@+id/custom_dialog_tv_confirm"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toRightOf="@id/custom_dialog_tv_cancel"
android:background="@drawable/common_custom_dialog_btn_selector"
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:text="取消"
android:textColor="@color/custom_dialog_text_bg_color_selector"
android:textSize="@dimen/custom_dialog_tv_text_size3" />
</RelativeLayout>

</RelativeLayout>

3、styles.xml中的CustomDialog样式代码如下所示：

<style name="CustomDialog" parent="@android:style/Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowBackground">@null</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:backgroundDimAmount">0.5</item>
</style>
