Viewflipper双击出现的firstview第三视图

编程问答 2022-04-26

问题描述

| 我是android的新手。我对视图翻转器功能有疑问。当我双击第一个视图出现的第三个视图，并且双击第二个视图而不是第三个视图的第一个视图时，我的视图脚蹼中有三个视图。如何停止此操作，以便双击也可以转到下一个视图，任何想法？ 这是代码 
public class gif extends Activity {
    ViewFlipper flipper;

    inFromTop.setDuration(1000);
    inFromTop.setInterpolator(new AccelerateInterpolator());
    return inFromTop;
    }

    Animation outtoBottom = new TranslateAnimation(
      Animation.RELATIVE_TO_PARENT,+1.0f

解决方法

        问题在于设置显示子级 在按钮button1上单击，您已经设置了
flipper.setDisplayedChild(0);
，这意味着将打开第一个视图。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法为零，则在每次单击时递增计数器，然后设置为不显示视图。这样，您可以处理双击事件。 谢谢 苏尼尔     ,        Jamesdroid我也遇到过同样的问题，该问题的解决方案是 1.OnClick功能检查在您的情况下按下了哪个button_tab，您有3个视图，分别是v1，v2和v3，现在还包括3个按钮，如按钮单击上的选项卡，您将显示相应的选项卡。 2.在内部按钮上再次单击，以检查当前视图是处于活动状态还是已显示，然后根据当前视图通过view.ShowNext（）转到所需视图。 以下是您推荐的代码，其中我有三个视图（view_beverages，view_dimsum，view_appetizers）和该视图的三个按钮（选项卡）。 ViewFlipper mVf =（ViewFlipper）findViewById（R.id.MyViewFlipper）; //我的ViewFilpper显示3个选项卡（1.饮料，2.DimSum，3。开胃菜） public void onClick（View v）{         //饮料标签点击         如果（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) {

        }

    }
