android - 对话框在android中 move ？

Question

我一直在 move 对话框。在这里，我发布了完整的源代码和屏幕截图。为什么我的对话框丢失了一部分。

代码:

public class MoveDialogBox extends Activity 
{
    Dialog dialog;
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                showDialog(1);
            }
        });
    }   
    @Override
    protected Dialog onCreateDialog( int id ) 
    { 
        switch ( id ) 
        {
            case 1:
                AlertDialog.Builder builder = null;
                Context mContext = this;
                LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
                View layout = inflater.inflate(R.layout.info, (ViewGroup) findViewById(R.id.root));
                Button exit = (Button) layout.findViewById(R.id.exit);
                exit.setOnClickListener(new View.OnClickListener() 
                {
                    @Override
                    public void onClick(View v) 
                    {
                        dismissDialog(1);
                    }
                });
                final LinearLayout LL = (LinearLayout) layout.findViewById(R.id.root);
                LL.bringToFront();
                LL.setOnTouchListener(new View.OnTouchListener() 
                {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) 
                    {
                        double X = event.getX();
                        double Y = event.getY();
                        String.valueOf(event.getX() + "x" + String.valueOf(event.getY()));
                        Toast.makeText(getBaseContext(), X + " : " + Y, Toast.LENGTH_SHORT).show();
                        LL.bringToFront();
                        LL.setX((float) X);
                        LL.setY((float) Y);
                        return false;
                    }
                });
                builder = new AlertDialog.Builder(mContext);
                builder.setView(layout);
                dialog = builder.create();
                dialog.setCanceledOnTouchOutside(true);
                break;
        }
        return dialog;
    }
}

请大家帮忙看看如何把对话框移到整个屏幕上。

我哪里错了。怎么解决。

您正在 move 对话框内的布局，您需要 move 对话框本身。

WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();
layoutParams.gravity = Gravity.TOP | Gravity.LEFT;
layoutParams.x = youNewX;
layoutParams.y = yourNewY;
dialog.getWindow().setAttributes(layoutParams);
