AlertDialog弹出框-常用几种写法

// AlertDialog不能new，没有构造器，但是里面的Builder内部类有new的方法
AlertDialog.Builder builder = new Builder(this);
// 设置图标，使用安卓自带的图标
builder.setIcon(android.R.drawable.alert_dark_frame);
// 设置标题
builder.setTitle("欲练此功必先自宫");
// 设置文本
builder.setMessage("李志平，想清楚哦");

// 设置确定按钮
builder.setPositiveButton("确定", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "感谢使用本软件,再见", 0).show();
}
});

// 设置取消按钮
builder.setNegativeButton("取消", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "若不自宫,一定不成功", 0).show();
}
});
// 使用创建器,生成一个对话框对象
AlertDialog ad = builder.create();
ad.show();

new AlertDialog.Builder(WeiListenRecordingStudioSoundEditActivity.this).setTitle("退出编辑").setMessage("退出编辑将会丢失编辑音乐，重新录音，确认退出？")
.setPositiveButton("离开编辑", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {

}
})
.setNegativeButton("继续编辑", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {

}
}) .show();
