Android 单击按钮启用和禁用广播接收器

我想在单击按钮时启用和禁用广播接收器以完成引导。。只有单击一次按钮，接收器才会响应。我确实看到了一些类似的问题，但没有一个答案奏效。。请帮忙

我试过这个代码，但没用

PackageManager pm  = getApplicationContext().getPackageManager();
ComponentName componentName = new ComponentName("mypackage", ".receivername");
pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

示例代码，您可以在中注册您的接收器onCreate方法和onDestroy方法取消注册它

    private BroadcastReceiver receiver;

    @Overrride
    public void onCreate(Bundle savedInstanceState){

      // your oncreate code

      IntentFilter filter = new IntentFilter();
      filter.addAction("SOME_ACTION");
      filter.addAction("SOME_OTHER_ACTION");

      receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
          //do something based on the intent's action
        }
      }

      registerReceiver(receiver, filter);
}

记住要在onDestroy方法中运行此操作：

@Override
protected void onDestroy() {
  unregisterReceiver(receiver); //unregisterReceiver can be anywhere based on your requirement
}

试试这个：

YourBroadcastReceiver mReceiver = new YourBroadcastReceiver();
IntentFilter filter = new IntentFilter();  //Filter for your receiver...
filter.addAction(your action goes here...);
registerReceiver(mReceiver , filter); **// Register**

unregisterReceiver(mReceiver );  **// Unregister**

试试这个

b1.setOnClickListener(new View.OnClickListener() {

     @Override
     public void onClick(View v) {
        // TODO Auto-generated method stub

            PackageManager pm  = Re_editActivity.this.getPackageManager();
            ComponentName componentName = new ComponentName(currentActivity.this, name_of_your_receiver.class);
            pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                            PackageManager.DONT_KILL_APP);
            Toast.makeText(getApplicationContext(), "activated", Toast.LENGTH_LONG).show();

            }
        });

b2.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            PackageManager pm  = Re_editActivity.this.getPackageManager();
            ComponentName componentName = new ComponentName(currentActivity.this, name_of_your_receiver.class);
            pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                            PackageManager.DONT_KILL_APP);
            Toast.makeText(getApplicationContext(), "cancelled", Toast.LENGTH_LONG).show();
        }
    });

此处按钮1用于激活广播接收器，按钮2用于停用广播接收器 你还需要在清单文件中注册你的广播接收器并设置

<receiver android:name="name_of_your_receiver" android:enabled="false">
        <intent-filter >                
            <action android:name="android.intent.action.BOOT_COMPLETED"/>                
        </intent-filter>
    </receiver>

我认为这样使用更容易：

public static void setAppComponentEnabled(@NonNull final Context context, @NonNull final Class<?> componentClass, final boolean enable) {
    final PackageManager pm = context.getPackageManager();
    final int enableFlag = enable ? PackageManager.COMPONENT_ENABLED_STATE_ENABLED : PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
    pm.setComponentEnabledSetting(new ComponentName(context, componentClass), enableFlag, PackageManager.DONT_KILL_APP);
}

public static void setAppComponentEnabled（@NonNull final Context Context，@NonNull final Class componentClass，final boolean enable）{
final-PackageManager pm=context.getPackageManager（）；
final int enableFlag=enable？PackageManager.COMPONENT_ENABLED_STATE_ENABLED：PackageManager.COMPONENT_ENABLED_STATE_DISABLED；
setComponentEnabledSetting（新的ComponentName（上下文，componentClass），enableFlag，PackageManager.DONT_KILL_APP）；
}

如果您已经找到了解决方案，请接受/投票支持答案：）谢谢您的时间和努力。。我试过这个按钮点击，但没有工作。。。
