android - 如何旋转TextView？

Question

我想旋转 TextView 但无法获得正确的输出。我得到的 textView 缺少一些文本

在布局中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_marginTop = "50dip">

<TextView android:layout_width="wrap_content" android:gravity="bottom"
    android:layout_height="wrap_content" android:id="@+id/text"
    android:text="Shreeji \n Nath" />

</RelativeLayout> 

在动画中

   <?xml version="1.0" encoding="utf-8"?>
   <rotate xmlns:android="http://schemas.android.com/apk/res/android"
        android:fromDegrees="40" android:toDegrees="-90" android:pivotX="40%"
        android:duration="0">
   </rotate>

Java 文件

import android.app.Activity;
import android.os.Bundle;
import android.view.animation.AnimationUtils;
import android.view.animation.RotateAnimation;
import android.widget.TextView;

public class VDemo extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    TextView tv = (TextView)findViewById(R.id.text);
    RotateAnimation ranim = (RotateAnimation)AnimationUtils.loadAnimation(this,R.anim.myanim);
    ranim.setFillAfter(true); 
    tv.setAnimation(ranim);

  }
}

在 API 级别 12 中添加

view.animate().rotationBy(90).start()
