Calculate view measure before display it

android, measure, size, view

Solution

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

Problem

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.
