一个ViewSwitcher，一个HorizontalScrollView，当ViewSwitcher切换内容时（调用showNext()）竟然会导致HorizontalScrollView也跟着滚动。
package inspur.hzt.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.widget.ViewSwitcher;
public class HSVActivity extends Activity {
ViewSwitcher switcher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hsv);
switcher = (ViewSwitcher) findViewById(R.id.viewSwitcher1);
//hsv = (HorizontalScrollView) findViewById(R.id.horizontalScrollView1);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DPAD_RIGHT || keyCode == KeyEvent.KEYCODE_DPAD_LEFT) {
View v = getCurrentFocus();
if (v.getId() == R.id.button1 || v.getId() == R.id.button2) {
switcher.showNext(); //这里竟然会导致HorizontalScrollView也跟着滚动，不知道如何解决
return true;
}
}
return super.onKeyDown(keyCode, event);
}
}
