option menu和onTouchEvent

本人使用魅族MX2 今天下午调了一个下午的bug 由于未知原因option menu 嵌套进Tab layout 无法显示menu键

其实在原生安卓上是正常的

而option menu单独使用 不嵌套进Tab layout也是正常的 

代码延续上一篇的

只是在ImgActivity中override了onTouchEvent，onCreateMenu 和onOptionsItemSelected

 

optionMenu部分

private static final String TAG = "com.example.hw2";
	
	private static final int OPTION1 = 1;
	private static final int OPTION2 = 2;
	private static final int OPTION3 = 3;
	private static final int OPTION4 = 4;
	private static final int OPTION5 = 5;
	private static final int OPTION6 = 6;


/* Creates the menu items */
	public boolean onCreateOptionsMenu(Menu menu) {
		menu.add(Menu.NONE, OPTION1, Menu.NONE, "Bookmark").setIcon(android.R.drawable.ic_menu_agenda);
		menu.add(Menu.NONE, OPTION2, Menu.NONE, "Save").setIcon(android.R.drawable.ic_menu_save);
		menu.add(Menu.NONE, OPTION3, Menu.NONE, "Search").setIcon(android.R.drawable.ic_menu_search);
		menu.add(Menu.NONE, OPTION4, Menu.NONE, "Share").setIcon(android.R.drawable.ic_menu_share);
		menu.add(Menu.NONE, OPTION5, Menu.NONE, "Delete").setIcon(android.R.drawable.ic_menu_delete);
		menu.add(Menu.NONE, OPTION6, Menu.NONE, "Preferences").setIcon(android.R.drawable.ic_menu_preferences);
		
		return true;
	}
	
	/* Handles item selections */
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) 
		{
			case OPTION1:
				Toast.makeText(getApplicationContext(), "Bookmark is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 1 selected");
				return true;
			case OPTION2:
				Toast.makeText(getApplicationContext(), "Save is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 2 selected");
				return true;
			case OPTION3:
				Toast.makeText(getApplicationContext(), "Search is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 3 selected");
				return true;
			case OPTION4:
				Toast.makeText(getApplicationContext(), "Share is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 4 selected");
				return true;
			case OPTION5:
				Toast.makeText(getApplicationContext(), "Delete is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 5 selected");
				return true;
			case OPTION6:
				Toast.makeText(getApplicationContext(), "Preferences is selected", Toast.LENGTH_SHORT).show();
				Log.i(TAG, "----------- Option 6 selected");
				return true;
		}
		return false;
	}

 

OnTouchEvent部分

这部分参照了 http://www.ourunix.org/android/post/82.html 多谢多谢！

@Override
	public boolean onTouchEvent(MotionEvent event) {
		// TODO Auto-generated method stub
		int touchEvent = event.getAction();
		
		switch(touchEvent){
			case MotionEvent.ACTION_DOWN:
				openOptionsDialog()
				Log.i(TAG, "MotionEvent.Action_down!!");
				break;
			default:
				break;
		}
	
		return super.onTouchEvent(event);
	}

	private void openOptionsDialog(){
		new AlertDialog.Builder(ImgActivity.this)
						.setTitle("Save File...")
						.setIcon(android.R.drawable.ic_menu_save)
						.setMessage("Do you want to save this file?").setPositiveButton("YES", new DialogInterface.OnClickListener() {							
							@Override
							public void onClick(DialogInterface dialog, int which) {
								// TODO Auto-generated method stub	
							}
						})
						.setNegativeButton("NO", new DialogInterface.OnClickListener() {
							
							@Override
							public void onClick(DialogInterface dialog, int which) {
								// TODO Auto-generated method stub	
							}
						})
					    .setNeutralButton("CANCEL", new DialogInterface.OnClickListener() {
							
							@Override
							public void onClick(DialogInterface dialog, int which) {
								// TODO Auto-generated method stub
								
							}
						})
						.show();
		
	}

 

之前一直不知道Log和TAG是做什么用的，现在终于知道了：在runtime的时候，在logcat中用的，Log.i可以用来debug
