android - 单击按钮启用和禁用广播接收器

Question

我想启用和禁用广播接收器以在单击按钮时完成启动。接收器在单击一次按钮之前不应响应。我确实看到了一些类似的问题，但没有一个答案有效..请帮助...

我试过这段代码但没用..

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

Answer 1

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();
        }
    });

这里 button1 用于激活广播接收器，button2 用于停用它 您还需要在 list 文件中注册您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>
