解锁Android手机编程？

问题描述

我想写关于如何编程解锁Android手机的code。

我要锁定或解锁手机，当用户点击接近传感器。

 公共类MyActivity延伸活动{

    私有静态最后弦乐ACTION =android.intent.action.ACTION_SCREEN_OFF;
    BroadcastReceiver的myReceiver;
    上下文语境;
    @覆盖
    保护无效的onCreate（包savedInstanceState）{
        // TODO自动生成方法存根
        super.onCreate（savedInstanceState）;
        上下文=这一点;
        最后的IntentFilter theFilter =新的IntentFilter（）;
        theFilter.addAction（ACTION）;

        context.registerReceiver（myReceiver，theFilter）;
        的System.out.println（里increate）;
        myReceiver =新的BroadcastReceiver（）{

            @覆盖
            公共无效的onReceive（上下文的背景下，意图意图）{
                // TODO自动生成方法存根
                    的System.out.println（手机锁定*****）;
            }

        };

    }}
 

解决方案

  @覆盖
    保护无效onResume（）{
        // TODO自动生成方法存根
        super.onResume（）;
         IntentFilter的过滤器=新的IntentFilter（Intent.ACTION_SCREEN_OFF）;
            registerReceiver（mIntentReceiver，过滤器）;
            的System.out.println（广播接收器注册****）;
    }

     私人的BroadcastReceiver mIntentReceiver =新的BroadcastReceiver（）{

        @覆盖
        公共无效的onReceive（上下文的背景下，意图意图）{
            // TODO自动生成方法存根

                的System.out.println（手机锁）;

        }
 

I want to write the code on how to unlock the Android Phone programmatically.

I want lock or unlock the phone when the user taps the proximity sensor.

public class MyActivity extends Activity{

    private static final String ACTION = "android.intent.action.ACTION_SCREEN_OFF";
    BroadcastReceiver myReceiver;
    Context context;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        context = this;
        final IntentFilter theFilter = new IntentFilter();
        theFilter.addAction(ACTION);

        context.registerReceiver(myReceiver, theFilter);
        System.out.println("inside increate");
        myReceiver = new BroadcastReceiver(){

            @Override
            public void onReceive(Context context, Intent intent) {
                // TODO Auto-generated method stub
                    System.out.println("phone locked*****");
            }

        };

    }}

解决方案

@Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
         IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
            registerReceiver(mIntentReceiver, filter);
            System.out.println("BROADcast receiver registered****");
    }

     private BroadcastReceiver mIntentReceiver = new BroadcastReceiver(){

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub

                System.out.println("phone locked");

        }
