position a viewstub programmatically
문제
i want to position a viewstub inside a viewgroup pogrammatically.
i tried using the setLayoutParams() method but its not available for viewstubs.
Please suggest any solution.
below is my code.
setContentView(R.layout.textplay);
bt = (Button) findViewById(R.id.button1);
bt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
panel = (ViewStub) findViewById(R.id.serachViewStub2);
panel.inflate(getApplicationContext(), R.layout.half_screen,null);
panel.setVisibility(View.VISIBLE);
panel.setOnInflateListener(new OnInflateListener() {
@Override
public void onInflate(ViewStub arg0, View arg1) {
// TODO Auto-generated method stub
parentLayout = (LinearLayout) findViewById(R.id.stubLayout1);
parentLayout.setLayoutParams(new LinearLayout.LayoutParams(0, 300));
}
});
}
});

해결책
After you inflate the ViewStub, you can access the layout which the ViewStub is actually showing. Get a reference to the layout and setLayoutparameters on it.
ViewStub inflates my_layout.xml which contains a LinearLayout with id as mainContainer. Once you inflate the viewstub, get a reference to the mainContainer and apply layout parameters on it.
다른 팁
suppose your ViewStub
is under a RelativeLayout
container, you can use the following code to set the layout parameters.
View view = ((ViewStub) findViewById(R.id.view_stub)).inflate();
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) view.getLayoutParams();
params.bottomMargin = 0;
params.topMargin = 50;
view.setLayoutParams(params);
I have try methods,the following would be work: After inflate the viewstub,you can get the viewstub's layout by its id,then its position could be set as you want.
//mViewStub is the viewstub
mViewStub.setVisibility(View.VISIBLE);
//view is parent of viewstub,
View viewstublayout = view.findViewById(R.id.viewstub_layout);
if (viewstublayout != null) {
viewstublayout.layout(l, t, r, b);
}
