我是android的新手。我对视图翻板功能有疑问。我在视图翻板中有三个视图，当我双击第一个视图第三个视图时出现，当我双击第二个视图而不是第三个视图时，第一个视图出现。如何阻止这一点，以便双击它也只会进入下一个视图，任何想法？
这是代码
public class gif extends Activity {
ViewFlipper flipper;
// RelativeLayout r1 = (RelativeLayout)findViewById(R.id.second_view);
private Animation inFromTopAnimation() {

Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f
);
inFromTop.setDuration(1000);
inFromTop.setInterpolator(new AccelerateInterpolator());
return inFromTop;
}
private Animation outToBottomAnimation() {

Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, +1.0f

问题在于设置显示子项
在按钮上单击ekgbutton您已设置flipper.setDisplayedChild(0);，这意味着将打开第一个视图。将其设为flipper.setDisplayedChild(2);
flipper.setDisplayedChild(0) = display first view
flipper.setDisplayedChild(1) = display second view
flipper.setDisplayedChild(2) = display third view

您可以创建一个hasmap，将cutton对象存储为键，然后单击counter作为值。如果计数器的模数除数为零，则在每次单击时递增计数器，然后设置取消显示视图。通过这种方式，您可以处理双击事件。

Jamesdroid我也遇到了同样的问题，问题的解决方案就是这样 1.单击功能检查按下哪个按钮_ 在你的情况下你有3个视图让它为v1，v2和v3现在也让你包括3个按钮，如按钮上的标签点击你将显示相应的标签。 2. 再次点击内部按钮，检查当前视图处于活动状态或显示，然后根据当前视图通过view.ShowNext（）进入所需视图。
以下是您推荐的代码，其中我有三个观看次数（view_beverages，view_dimsum，view_appetizers）和theree按钮（标签）。
ViewFlipper mVf =（ViewFlipper）findViewById（R.id.MyViewFlipper）; //我的ViewFilpper显示3个标签（1.Beverages，2.DimSum，3.Appetizers） public void onClick（查看v）{ // Beverages选项卡点击 if（v == btn_beverages）{
btn_beverages.setBackgroundResource(R.drawable.beverages_on);
btn_dimsum.setBackgroundResource(R.drawable.dimsum_off);
btn_appetizers.setBackgroundResource(R.drawable.appetizers_off);
View myCurrentView = mVf.getCurrentView();//Collecting the current displayed view.
if (myCurrentView == view_beverages) {
}
if (myCurrentView == view_dimsum) {
mVf.showNext();
mVf.showNext();
}
if (myCurrentView == view_appetizer) {
mVf.showNext();
}
}
// Dimsum tab click
if (v == btn_dimsum) {
btn_beverages.setBackgroundResource(R.drawable.beverages_off);
btn_dimsum.setBackgroundResource(R.drawable.dimsum_on);
btn_appetizers.setBackgroundResource(R.drawable.appetizers_off);
View myCurrentView = mVf.getCurrentView();
if (myCurrentView == view_beverages) {
mVf.showNext();
}
if (myCurrentView == view_dimsum) {
}
if (myCurrentView == view_appetizer) {
mVf.showNext();
mVf.showNext();
}
}
// Appetizer tab click
if (v == btn_appetizers) {
btn_beverages.setBackgroundResource(R.drawable.beverages_off);
btn_dimsum.setBackgroundResource(R.drawable.dimsum_off);
btn_appetizers.setBackgroundResource(R.drawable.appetizers_on);
View myCurrentView = mVf.getCurrentView();
if (myCurrentView == view_beverages) {
mVf.showNext();
mVf.showNext();
}
if (myCurrentView == view_dimsum) {
mVf.showNext();
}
if (myCurrentView == view_appetizer) {
}
}
