Text Rotation in Android

In Android we can rotate text view after API Level 11 .

In android sdk using public void setRotation (float rotation) method
on Textview we can rotate Text.
and here rotation parameter is The degrees of rotation.

Example:
In below example we can see diffrence between normal TextView and rotated TextView.

UI Layout(text_roation.xml)


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/rotationtextview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="androidsurya(RotationText)"
        android:textColor="#00FF00"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/normaltextview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/normaltextview"
        android:layout_alignParentTop="true"
        android:layout_marginTop="18dp"
        android:text="androidsurya(NormalText)"
        android:textColor="#00FF00"
        android:textStyle="bold" />

</RelativeLayout>

Android Activity(TextRoationActivity.java)


package com.androidsurya.textrotation;

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

public class TextRoationActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.text_roation);
        TextView rotationTextview = (TextView) findViewById(R.id.rotationtextview);
        rotationTextview.setRotation(85);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.text_roation, menu);
        return true;
    }

}

Register Activity in AndroidManifest file


<activity
            android:name="com.androidsurya.textrotation.TextRoationActivity"
            android:label="@string/app_name" >

Output Screenshot:




Note : In AndroidManifest file minsdk level should be "11"
    <uses-sdk
        android:minSdkVersion="11" />
