我在android中的新功能。 这是交易。我希望让我的活动像GameCih菜单栏（就像所有活动一样，我可以绕过应用程序，做我想做的任何事情，菜单栏仍在上面） 但我想做的与GameCIH并不完全相同。我想要音乐播放器，所以我可以播放歌曲，显示专辑封面，并通过触摸在屏幕上移动播放器菜单。 这是我的主要活动：
public class MainActivity extends Activity implements OnTouchListener{
RelativeLayout rel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
rel = (RelativeLayout) findViewById(R.id.myactivity);
rel.setOnTouchListener(this);
this.setFinishOnTouchOutside(false);
this.getWindow().setBackgroundDrawable(new ColorDrawable(0));
Window dialogWindow = this.getWindow();
// Make the dialog possible to be outside touch
dialogWindow.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
dialogWindow.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
Button btn =(Button)findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
finish();
}
});
Thread th = new Thread(){
public void run (){
try {
while(true){
Thread.sleep(10000);
try{
Intent i=new Intent(getApplicationContext(),MainActivity.class);
//i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(i);
}catch(Exception ex){
Log.d("X",ex.getMessage());
}
}
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
th.start();
}
@Override
public void onBackPressed() {
// Do Here what ever you want do on back press;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
if(rel==arg0){
switch(arg1.getAction())
{
case MotionEvent.ACTION_MOVE:
{
WindowManager.LayoutParams layoutParams = this.getWindow().getAttributes();
layoutParams.gravity = Gravity.TOP | Gravity.LEFT;
layoutParams.x = ((int) arg1.getRawX()-400);
layoutParams.y = ((int) arg1.getRawY()-200);
this.getWindow().setAttributes(layoutParams);
return true;
}
case MotionEvent.ACTION_UP:
{
WindowManager.LayoutParams layoutParams = this.getWindow().getAttributes();
layoutParams.gravity = Gravity.TOP | Gravity.LEFT;
layoutParams.x = ((int) arg1.getRawX()-400);
layoutParams.y = ((int) arg1.getRawY()-200);
this.getWindow().setAttributes(layoutParams);
return true;
}
case MotionEvent.ACTION_DOWN:
{
WindowManager.LayoutParams layoutParams = this.getWindow().getAttributes();
layoutParams.gravity = Gravity.TOP | Gravity.LEFT;
layoutParams.x = ((int) arg1.getRawX()-400);
layoutParams.y = ((int) arg1.getRawY()-200);
this.getWindow().setAttributes(layoutParams);
return true;
}
}
}
return false;
}
}
和xml
