我一直在移动对话框。在这里,我发布了我的完整源代码和屏幕截图。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;
}
}
