我在Seekbar上有一个带有选框效果的textview。 这是我的搜索栏听众。
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (mediaPlayer != null && fromUser) {
mediaPlayer.seekTo(progress * 1000);
}
}
});
因此，当我使用搜索栏进行搜索时，上面的文本视图会使用选框文本刷新。所有手机都不会发生这种情况。
以下几行仅为textview编写：
textView.setSelected(true);
textView.setText("aaaaa bbbbbbb ccccccc ddddddddd eeeeeeee ffffffff gggggggg");
这是我的xml的一部分：
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content" android:id="@+id/seekBar"
android:layout_centerVertical="true"
android:layout_toLeftOf="@+id/tog"
android:layout_toRightOf="@+id/imageView"
android:layout_toEndOf="@+id/imageView"
android:layout_marginRight="60dp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textColor="#ffffff"
android:id="@+id/songName"
android:text="Song Name"
android:layout_alignTop="@+id/imageView"
android:layout_toRightOf="@+id/imageView"
android:layout_marginLeft="5dp"
android:layout_marginRight="50dp" />
我不知道为什么在我寻找的时候文本视图会被刷新。我该如何解决这个问题？我寻求帮助!! TIA
编辑：我认为再次提到某些手机出现问题是明智之举。完整代码：

telapsed = (TextView)findViewById(R.id.elapsedtime);
seekBar = (SeekBar)findViewById(R.id.seekBar);
tg = (ToggleButton)findViewById(R.id.tog);
textView.setSelected(true);
textView.setFocusable(false);
textView.setText("aaaaa bbbbbbb ccccccc ddddddddd eeeeeeee ffffffff gggggggg");
textView.setText("Tobu bhoy nei maa amra protibad korte jani");
