BroadcastReceiver class 不是 运行
BroadcastReceiver class not running
我写了一个 BroadcastReceiver
class 用于在断开充电器时接收广播意图,但当我断开充电器时它不显示 Toast。
Logcat 也不显示任何内容。我通过 wifi 使用 ADB。
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class My extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
Toast.makeText(arg0, "hello", Toast.LENGTH_LONG).show();
}
}
这是我的清单

将您在 android 清单中的操作更改为:
<action android:name="android.intent.action.ACTION_POWER_CONNECTED" />
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" />
