自定义的静态广播没有作用怎么办?
//在AndroidManifest.xml里注册静态广播
<receiver android:name=".TestBroadcast">
<intent-filter>
<action android:name="com.lpj.test"/>
</intent-filter>
</receiver>
//定义广播接收类
public class TestBroadcast extends BroadcastReceiver {
public static final String RECEIVER = "com.lpj.test";
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(RECEIVER)){
Log.i("BroadcastTest", "Broadcast Start!");
Toast.makeText(context, "Broadcast Start!",
Toast.LENGTH_LONG).show();
}
}
}
//在主界面里发送广播
public class replyer extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_replyer);
this.findViewById(R.id.button).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
sendBroadcast(new Intent("com.lpj.test"));
}
});
}
}
结果没有任何反应(既不弹出Toast,logcat里也没东西),4.2系统,真机和模拟器都测试过 广播 Broadcast android broadcastreceiver
[解决办法]sendBroadcast(new Intent("com.lpj.test"));
写错了。
这样写
sendBroadcast(new Intent(this,TestBroadcast.class));
[解决办法] Intent intent = new Intent();
intent.setAction("com.lpj.test");
sendBroadcast(intent);
[解决办法]
Intent intent = new Intent();
intent.setAction("com.lpj.test");
sendBroadcast(intent);
像楼上说的这样就可以,如果你的receiver不是在activity里面你把context 改成getApplication().getContext();
[解决办法]sendBroadcast(new Intent(replyer.this, "com.lpj.test"));
或者
sendBroadcast(new Intent(replyer.this.getApplicationContext(), "com.lpj.test"));
楼上说的也都行!
