Setcontentview By Using Extending View Class

I am using extends View for setting content of an activity..what is happening it is showing blank activity.instead of setting text. public class ThreadCheck extends Activity{

Solution 1:

Change this

view=new MyView(ctx);

to

view=new MyView(ThreadCheck.this);

And change to

publicclassMyViewextendsTextView{

    publicMyView(Context context) {
        super(context);
        this.setText("Hello This Is Myview");
    }

}

Edit: to the question in comment. You need a ViewGroup to which you add your views.

publicclassMyViewextendsRelativeLayout{

        publicMyView(Context context) {
            super(context);


            RelativeLayout.LayoutParamslayoutParams=newRelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
            this.setLayoutParams(layoutParams);

            RelativeLayout.LayoutParamsparams1=newRelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

            TextViewtv=newTextView(context);
            tv.setText("hello");
            tv.setId(1);

            Buttonb=newButton(context);
            params1.addRule(RelativeLayout.BELOW, tv.getId());
            b.setText("Hi");
            b.setId(2);

            this.addView(tv);
            this.addView(b, params1);

        }
    }
