So I’m writing an app, and for some reason I get a Runtime exception when I try to get the height of a FrameLayout. I use weight quite a bit throughout the design, so I wanted to double check they were the height I needed them to be.
Here is my main Activity:
package com.app.conekta;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.Toast;
public class Conekta extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onStart() {
super.onStart();
FrameLayout fl1 = (FrameLayout) findViewById(R.id.headerFrameLayout);
//Button b=(Button) findViewById(R.id.searchButton);
Toast.makeText(Conekta.this, fl1.getHeight(), Toast.LENGTH_SHORT).show();
}
}
And this is my XML:

Any idea why this is happening?
