android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"

</LinearLayout>


Java code, call setRotation() to display the TextView (verticalTextView) in vertical.
package com.example.androidtextview;

import android.os.Bundle;
import android.app.Activity;
import android.widget.TextView;

public class MainActivity extends Activity {

TextView verticalTextView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

verticalTextView = (TextView)findViewById(R.id.verticaltextview);
verticalTextView.setRotation(90);
}


}


remark: Have to modify AndroidManifest.xml to set android:minSdkVersion="11" or higher.
