Remove all items inside linearlayout

Hi Please try this code its working for me

public class ShowText extends Activity {
    /** Called when the activity is first created. */
    LinearLayout linearLayout;
    TextView textView,textView1;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        textView=new TextView(this);
        textView1=new TextView(this);
        textView.setText("First TextView");
        textView1.setText("First TextView");

        linearLayout=(LinearLayout) findViewById(R.id.mn);
        linearLayout.addView(textView);
        linearLayout.addView(textView1);
        linearLayout.removeAllViews();

    }
}

Why you wrote linearLayout.getParent()?

You should call this directly on LinearLayout:

linearLayout.removeAllViews();
