CustomView in android throws inflate exception

Question

I have to create a custom view in my android application, for that I have wrote code as follows

xml

<com.package.custom.CustomView
    android:id="@+id/my_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

CustomView.java

package com.package.custom;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.view.View;

public class CustomView extends View {

    Paint customPaint;

    public CustomView(Context context) {
        super(context);
        customPaint = new Paint();
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        int width = this.getMeasuredWidth();
        int height = this.getMeasuredHeight();
        customPaint.setStyle(Paint.Style.FILL);
        customPaint.setAntiAlias(true);
        customPaint.setColor(getResources().getColor(android.R.color.holo_blue_dark));
        canvas.drawPaint(customPaint);
    }
}

Activity

public class CustomViewActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom_button);
        CustomView customView = (CustomView) findViewById(R.id.my_view);

    }   
}

but while I am running the application I am getting error ::

3178-3178/com.package.custom E/AndroidRuntime﹕ FATAL EXCEPTION: main
    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.package.custom/com.package.custom.CustomViewActivity}: android.view.InflateException: Binary XML file line #11: Error inflating class com.package.custom.CustomView
            at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2255)

What is the reason ? is there any problem in my code ? how do I resolve this ?

Answer 1

Try to change:

public class CustomView extends TextView {

    Paint customPaint;

    public CustomView(Context context, AttributeSet attrs) {
    super(context, attrs);
    customPaint = new Paint();
}

Name of the class constructor are not the same.

View class does not have method android:text="" change base class to TextView
