I have created a custom TextView and the only thing I did is I put one "instance" in the layout xml. This causes to crash the app with an "Inflate Exception" :
Here's the complete custom class (actually there is nothing "custom" in it yet...):
package com.example.TestApp;
...
public class MyTextView extends TextView {
public MyTextView (Context context) {
super(context);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec); }
@Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
}
}
The complete layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.example.TestApp.MyTextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, MyActivity"
/>
</LinearLayout>
The log is:
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example.TestApp/com.example.TestApp.MyActivity}:
android.view.InflateException: Binary XML file line #8: Error inflating class

I have read through many posts about these inflate exceptions, but this time it's really the most easist case. The class path used in xml (com.example.TestApp.MyTextView) seems to be correct - Intellj IDEA even suggested it...
Btw: The min target sdk version is set to 10.
add constructor like this
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
Hope this helps
add constructor
public MyTextView(Context context, AttributeSet attrs)
