启用和禁用按钮点击广播接收器 [英] enable and disable broadcast receiver on button click

问题描述

我想启用和禁用广播接收机开机完整的按钮点击。该接收器应该没有回应，直到被点击一次按钮。我确实看到了一些类似的问题，但无答案的工作..请帮助...

我想这code，但没有奏效。

  PackageManager PM = getApplicationContext（）getPackageManager（）。
组件名组件名=新的组件名（mypackage中，.receivername）;
pm.setComponentEnabledSetting（组件名，PackageManager.COMPONENT_ENABLED_STATE_DISABLED，PackageManager.DONT_KILL_APP）;
 

解决方案

试试这个

  b1.setOnClickListener（新View.OnClickListener（）{

     @覆盖
     公共无效的onClick（视图v）{
        // TODO自动生成方法存根

            PackageManager下午= Re_editActivity.this.getPackageManager（）;
            组件名组件名=新的组件名（currentActivity.this，name_of_your_receiver.class）;
            pm.setComponentEnabledSetting（组件名，PackageManager.COMPONENT_ENABLED_STATE_ENABLED，
                            PackageManager.DONT_KILL_APP）;
            Toast.makeText（getApplicationContext（），激活，Toast.LENGTH_LONG）.show（）;

            }
        }）;

b2.setOnClickListener（新View.OnClickListener（）{

        @覆盖
        公共无效的onClick（视图v）{
            // TODO自动生成方法存根
            PackageManager下午= Re_editActivity.this.getPackageManager（）;
            组件名组件名=新的组件名（currentActivity.this，name_of_your_receiver.class）;
            pm.setComponentEnabledSetting（组件名，PackageManager.COMPONENT_ENABLED_STATE_DISABLED，
                            PackageManager.DONT_KILL_APP）;
            Toast.makeText（getApplicationContext（），取消，Toast.LENGTH_LONG）.show（）;
        }
    }）;
 

下面按钮1用于激活广播接收器和按钮2至停用  此外ü需要注册广播接收器清单文件，并设置

 ＆LT;接收器的Andr​​oid版本：NAME =name_of_your_receiver机器人：启用=假＆GT;
        ＆LT;意向滤光器＆gt;
            ＆lt;作用机器人：名称=android.intent.action.BOOT_COMPLETED/＆GT;
        ＆所述; /意图滤光器＆gt;
    ＆LT; /接收器＆GT;
 

i want to enable and disable broadcast receiver for boot complete on button click.. The receiver shouldn't respond until button is clicked once. i did see some similar questions but non of the answers worked.. please help...

i tried this code but didn't work..

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

解决方案

Try this

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();
        }
    });

here button1 is used to activate broadcast receiver and button2 to deactivate it Also u need to register your broadcast receiver in manifest file and set

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