代码如下：

package com.broadcasttest.broadcastreciver;

import android.app.AlertDialog;

import android.app.AlertDialog.Builder;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.DialogInterface;

import android.content.DialogInterface.OnClickListener;

import android.content.Intent;

import android.util.Log;

import android.view.WindowManager;

import android.widget.Toast;

public class BroadCastMain extends BroadcastReceiver {
public BroadCastMain() {
Log.i("TAG", "构造");
}

@Override
public void onReceive(Context context, Intent intent) {
Boolean tempBoolean = intent.getBooleanExtra("", true);
Log.i("TAG1", "tempBoolean:" + tempBoolean);
String str = intent.getStringExtra("msg");
AlertDialog.Builder builder = new Builder(context);
builder.setTitle(str);
builder.setNegativeButton("确定", new OnClickListener() {

@Override
public void onClick(DialogInterface arg0, int arg1) {
arg0.dismiss();
}
});
AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();

// try {

// Thread.sleep(5000);

// } catch (InterruptedException e) {

// // TODO Auto-generated catch block

// e.printStackTrace();

// }

Toast.makeText(context, str, 1000).show();
}

}

解决办法：

加权限:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
