Question

我在禁用广播接收器方面遇到了问题。广播接收器接收呼入和呼出呼叫。在我的情况下，当开关接通时，接收器应该在开关处于关闭状态时接收数据，接收器应该停止接收数据。

     switches.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {

//                sharedPreferences = getApplicationContext().getSharedPreferences("enableApp", Context.MODE_PRIVATE);
//                SharedPreferences.Editor editor = sharedPreferences.edit();
//                editor.putBoolean(getString(R.string.enable), isChecked);
//                editor.commit();


                if(isChecked)
                {

                    Toast.makeText(getApplicationContext(), "Enabled", Toast.LENGTH_SHORT).show();
                }
                else
                {
                    PackageManager pm  = DashBoardActivity.this.getPackageManager();
                    ComponentName componentName = new ComponentName(DashBoardActivity.this, CallReceiver.class);
                    pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                            PackageManager.DONT_KILL_APP);
                    Toast.makeText(getApplicationContext(), "cancelled", Toast.LENGTH_LONG).show();
                    Toast.makeText(getApplicationContext(), "Disabled", Toast.LENGTH_SHORT).show();


                }
            }
        });

这是我尝试过的代码，我尝试使用包管理器来禁用广播接收器。

The broadcast receiver registered in manifestfile
     <receiver android:name=".receiver.CallReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
        </receiver>

我想在我的活动中禁用接收器。如何禁用接收器？

试试这个，下面的代码可以解决你的问题，

 switches.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {

            sharedPreferences = getApplicationContext().getSharedPreferences("enableApp", Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = sharedPreferences.edit();
            editor.putBoolean(getString(R.string.enable), isChecked);
            editor.commit();


            if(isChecked)
            {
                PackageManager pm  = DashBoardActivity.this.getPackageManager();
                ComponentName componentName = new ComponentName(DashBoardActivity.this, CallReceiver.class);
                int status = getApplicationContext().getPackageManager().getComponentEnabledSetting(componentName);
                pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                        PackageManager.DONT_KILL_APP);
                Log.e("Broadcast status",status + "");
                Toast.makeText(getApplicationContext(), "Enabled", Toast.LENGTH_SHORT).show();


            }
            else
            {


                PackageManager pm  = DashBoardActivity.this.getPackageManager();
                ComponentName componentName = new ComponentName(DashBoardActivity.this, CallReceiver.class);
                int status = getApplicationContext().getPackageManager().getComponentEnabledSetting(componentName);
                pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                        PackageManager.DONT_KILL_APP);
                Log.e("Broadcast status",status + "");
                Toast.makeText(getApplicationContext(), "cancelled", Toast.LENGTH_LONG).show();
                Toast.makeText(getApplicationContext(), "Disabled", Toast.LENGTH_SHORT).show();


            }
        }
    });
