相关疑难解决方法(0)

我想知道我是否可以覆盖背部和主页按钮的动作是一些情况.通常这些按钮应该像往常一样反应,但在某些情况下,某些设置为真,我想覆盖按钮并让它们调用我自己的方法.

我使用这两种方法来覆盖这些按钮:

  @Override
  public void onBackPressed() {    
  // call my backbutton pressed method when boolean==true
    }

  @Override
  public void onAttachedToWindow()    {                                                                                       this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);    
   super.onAttachedToWindow(); 
   // call my homebutton pressed method when boolean==true
   }

我想禁用菜单按钮.我读了很多文章,没有任何作品.
我甚至无法检测菜单按钮按下的事件.覆盖onKeyDown(),onKeyUp(),onPrepareOptionsMenu(),onCreateOptionsMenu()等方法无法正常工作.我真的很绝望,请帮忙.

public class MainActivity extends Activity{
TranslateAnimation animateTopLayer;
Button btnOk;
ImageView ivLockMechanism;
ViewGroup rlTopLayer;
FramesSequenceAnimation anim;

@Override
public void onAttachedToWindow() {
    getWindow().addFlags(WindowManager.LayoutParams. FLAG_DISMISS_KEYGUARD);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent lockServiceIntent = new Intent(getApplicationContext(),LockService.class);
    startService(lockServiceIntent);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.test);
    rlTopLayer = (ViewGroup) findViewById(R.id.rlTopLayer);
    ivLockMechanism = (ImageView) findViewById(R.id.ivLockMechanism);
    btnOk = (Button) findViewById(R.id.btnOk);
    btnOk.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            rlTopLayer.startAnimation(animateTopLayer);
        }
    });
    Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.pg_0);
    ivLockMechanism.setImageBitmap(b);
    anim = AnimationsContainer.getInstance().unlockMechanismAnimation(ivLockMechanism);
    animateTopLayer = new TranslateAnimation(0, …

有没有办法与长按主页按钮时出现的最近的应用列表进行交互？我想完全关闭它,或者如果无法清除条目.
