在xml中設置錯誤膨脹類錯誤

Question

我試圖創建一個textView，它在屏幕上滑動並創建一個錯誤，但我不知道爲什麼。這是我的xml：

<set xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:fillAfter="true"> 

    <scale 
     android:duration="500" 
     android:fromXScale="1.0" 
     android:fromYScale="1.0" 
     android:interpolator="@android:anim/linear_interpolator" 
     android:toXScale="1.0" 
     android:toYScale="0.0" /> 

    <TextView 
     android:id="@+id/scroll_message" 
     android:text="@string/scroll_text" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:layout_gravity="center" 
     android:minLines="1" 
     android:maxLines="10" 
     android:width="250dp" 
     android:textColor="@android:color/black" 
     android:textStyle="bold" /> 

</set> 

而且我activty類：

package com.example.rsa.myapplication; 

import android.app.Activity; 
import android.os.Bundle; 
import android.text.method.ScrollingMovementMethod; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.content.Intent; 
import android.widget.EditText; 
import android.widget.TextView; 
import android.widget.ScrollView; 


public class MyActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_my); 
     //TextView txt = (TextView) findViewById(R.id.scroll_message); 
} 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 

     getMenuInflater().inflate(R.menu.activity_my, menu); 
     return true; 
    } 
} 

給出的錯誤是：

什麼會導致這個錯誤？

Answer 1

使用動畫代碼集，這樣的：

public void onResume(){ 
    super.onResume(); 
    textView.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.slide_up)); 
}
