我正在尝试同时滑动两个 TextView。这些 TextViews 在一个 RelativeLayout 中,一个在另一个旁边。第一个动画很干净。但是当我再次单击时,在两个文本视图之间运行动画时会形成间隙。
这是我在布局中的 xml 文件(activity_main.xml)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<TextView
android:id="@+id/TextView01"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#f00"
android:gravity="center" />
<TextView
android:id="@+id/TextView02"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000" />
</RelativeLayout>
MainActivity.java :
public class MainActivity extends Activity implements AnimationListener {
TextView txtView1;
TextView txtView2;
double counter = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
:
:
txtView1 = (TextView) findViewById(R.id.TextView01);
txtView2 = (TextView) findViewById(R.id.TextView02);
// load the animation
:
:
txtView1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (counter == 0) {
txtView2.setVisibility(View.VISIBLE);
txtView2.startAnimation(blackLeft);
txtView1.startAnimation(redLeft);
counter++;
} else {
txtView2.setVisibility(View.VISIBLE);
txtView2.startAnimation(blackRight);
txtView1.startAnimation(redRight);
counter--;
}
}
});
}
