AlertDialog使用和自定义

一、使用系统样式

AlertDialog.Builder builder = new AlertDialog.Builder(PaperActivity.this);

builder.setMessage(message);
builder.setTitle("提示");

builder.setPositiveButton("确认", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});

builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});

builder.create().show();

二、使用自定义样式

自定义style

<style name="AlertDialogCustom" parent="android:Theme.Material.Dialog.Alert">
<item name="android:textColor">#ffffff</item>
<item name="android:typeface">monospace</item>
<item name="android:textSize">10sp</item>
</style>

使用自定义

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(PaperActivity.this, R.style.AlertDialogCustom));

三、自定义Dialog

1.Dialog布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="40px"
android:minWidth="300px"
android:orientation="vertical">

<TextView
android:id="@+id/paper_dialog_titleText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="@color/colorAccent"
android:text="提示"
android:textSize="@dimen/alertDialogTitle"/>

<TextView
android:id="@+id/paper_dialog_contentText"
android:layout_width="match_parent"
android:minHeight="100px"
android:layout_height="wrap_content"
android:text="nihao"
android:textSize="@dimen/alertDialogText"/>

<Button
android:id="@+id/paper_dialog_checkButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="确定"
android:gravity="center"
android:background="@drawable/paper_dialog_checkbutton_selector"
android:textSize="@dimen/alertDialogCheck"
android:textColor="@color/colorAccent"/>

</LinearLayout>

2. 自定义Dialog的java

public class PaperDialog extends Dialog {

private Context mContext;
private TextView mTitle;
private TextView mContent;
private Button mCheckButton;

public PaperDialog(Context context) {
super(context);
mContext = context;
}

public PaperDialog(Context context, int themeResId) {
super(context, themeResId);
mContext = context;
}

protected PaperDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
}

public void createDialog(){
//获得inflater
LayoutInflater inflater = LayoutInflater.from(mContext);
//从xml转换为View
View layoutView = inflater.inflate(R.layout.question_paper_dialog, null);
//PaperDialog将layoutView作为其View
addContentView(layoutView,
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));//View的大小
//标题
mTitle = (TextView) layoutView.findViewById(R.id.paper_dialog_titleText);
//内容
mContent = (TextView) layoutView.findViewById(R.id.paper_dialog_contentText);
//确认按钮
mCheckButton = (Button) layoutView.findViewById(R.id.paper_dialog_checkButton);
}

public void setTitle(String title){
this.mTitle.setText(title);
}

public void setTitleSize(float size){
this.mTitle.setTextSize(size);
}
public void setMessage(CharSequence message) {
mContent.setText(message);
}

public void setMessageSize(float size){
this.mContent.setTextSize(size);
}

public void setCheck(CharSequence checkContent) {
mCheckButton.setText(checkContent);
}

public void setCheckSize(float size){
this.mCheckButton.setTextSize(size);
}

public void setCheckOnClickListener(String check, View.OnClickListener onClickListener){
this.mCheckButton.setText(check);
mCheckButton.setOnClickListener(onClickListener);
}

}

3.对自定义Dialog进行使用

PaperDialog paperDialog = new PaperDialog(PaperActivity.this,  R.style.AlertDialogCustom);
paperDialog.createDialog();
//显示“提示”
paperDialog.setTitle("提示");

String msg = "没有完成，无法提交试卷！";
//设置信息
paperDialog.setMessage(msg);
//设置确认监听器
paperDialog.setCheckOnClickListener("确认", new View.OnClickListener() {
@Override
public void onClick(View v) {
paperDialog.dismiss();
}
});
//显示Dialog
paperDialog.show();

4.style和dimens.xml

<style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert">
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
</style>

<!-- question begin -->
<dimen name="alertDialogTitle">30dp</dimen>
<dimen name="alertDialogCheck">30dp</dimen>
<dimen name="alertDialogText">25dp</dimen>
<!-- question end -->
