如果文本在另一個TextView中發生更改，TextView文本動畫將重新啓動

在TextView1中，文本動畫從右向左運行，並且在TextView2中不斷更改文本。問題是，當我在文本動畫TextView1重新啓動時執行TextView2.setText（「...」）。是否有可能阻止重新開始動畫？如果文本在另一個TextView中發生更改，TextView文本動畫將重新啓動

XML代碼TextView1：

<TextView 
android:id="@+id/artistAlbum" 
android:layout_width="wrap_content" 
android:layout_height="24dp" 
android:ellipsize="marquee" 
android:focusable="true" 
android:focusableInTouchMode="true" 
android:marqueeRepeatLimit="marquee_forever" 
android:paddingTop="2dp" 
android:scrollHorizontally="true" 
android:singleLine="true" 
android:text="text text text text text text text" 
android:textSize="14sp" />

Java代碼初始化TextView1：

final TextView textView1 = (TextView) rootView.findViewById(R.id.textView1); 
textView1.setSelected(true);

XML代碼TextView2：

<TextView 
    android:id="@+id/seekSongDuration" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentStart="true" 
    android:clickable="true" 
    android:paddingBottom="12dp" 
    android:paddingEnd="2dp" 
    android:paddingStart="10dp" 
    android:paddingTop="12dp" 
    android:text="0%" 
    android:textSize="20sp" />

     songArtistAlbum.setSelected(true); 

txtSeek = (TextView) rootView.findViewById(R.id.seekSongDuration); 
... 
} 
    private DiscreteSeekBar.OnProgressChangeListener onDurationProgressChangeListener = new DiscreteSeekBar.OnProgressChangeListener() {

      if (!fromUser) { 
       txtSeek.setText(Total.msecTo_MM_SS(seekBar.getProgress())); 
      } 
     } 

     @Override 
     public void onStartTrackingTouch(DiscreteSeekBar seekBar) { 
     } 

     @Override 
     public void onStopTrackingTouch(DiscreteSeekBar seekBar) { 
      txtSeek.setText(Total.msecTo_MM_SS(seekBar.getProgress())); 
     }

嘗試用LinearLayout包裝TextView1。

它幫助我。但問題是什麼？爲什麼在RelativeLayout動畫中重新啓動，並且在LinearLayout中沒有？ – Novah

檢查Activity類TextView對象及其賦值id。

有動畫工作的名爲'setSelected（true）'的對象的Java代碼。我不明白問題是什麼。 – Novah

加你java代碼和XML代碼，所以確切檢查有什麼問題 –

我加了java和xml代碼 – Novah

如果文本在另一個TextView中發生更改，TextView文本動畫將重新啓動
