I am trying to add views to LinearLayout dynamically as much as it possible (depending on screen width).
I do this before the LinearLayout displays on screen.
My LinearLayout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:background="#666"/>
My view to display in LinearLayout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:background="#999">
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:src="@drawable/no_photo"/>
</FrameLayout>
I add views to layout:
int allItems = 50;
int currentItem = 0;
while(currentItem < allItems)
{
FrameLayout view = (FrameLayout) inflater.inflate(R.layout.fl, null);
linearLayout.addView(view);
if (linearLayout.getMeasuredWidth() >= this.getWidth())
{
linearLayout.removeView(view);
break;
}
}
but linearLayout.getMeasuredWidth() and this.getWidth() is 0;
I know, that i must use View.measure method to calculate view size before it became visible, but i don't know where and how it use.
Edit your code as below :
Display display = getWindowManager().getDefaultDisplay();
int maxWidth = display.getWidth();
int widthSoFar=0;
int allItems = 50;
int currentItem = 0;
while(currentItem < allItems) {
FrameLayout view = (FrameLayout) inflater.inflate(R.layout.fl, null);
linearLayout.addView(view);
view .measure(0, 0);
widthSoFar = widthSoFar + view.getMeasuredWidth();
if (widthSoFar >= maxWidth) {
linearLayout.removeView(view);
break;
}
}
Hope this helps you
