Question

我有一个listview包含项目Apple，Banana，Orange ......在第二个屏幕activity 当我点击Apple上的特定项目时，它会导航到详细信息屏幕

此处输出必须通过单击 - ＆gt;来显示苹果..如果我刷页面然后香蕉和下一次刷橙色

苹果 - ＆GT;香蕉 - ＆GT;橙

如果我点击Banana - ＆gt;然后它必须显示为香蕉然后离开苹果..并右键滑动...橙色。

我在第二个屏幕中点击（Banana）listview的项目，它必须显示在详细信息屏幕上，左侧滑动上一个列表项目，右键滑动列表中的下一个项目。

Banana - ＆gt;用于向左滑动Apple - ＆gt;右滑动橙色

如果我点击橙色 - ＆gt;然后它必须显示为橙色然后离开滑动香蕉..并为下一个左滑动...橙色。香蕉

橙色 - ＆gt;用于左侧滑动香蕉---＆gt;用于下一次左侧滑动 - ＆gt; Apple

但是我得到像Apple这样的输出 - ＆gt; Banana - ＆gt; Orange，点击了listview ....

每个项目的所有案例

Answer 1

在OnItemClickListener的水果列表中，您应该在Intent中传递所选水果的位置，这样您就可以在详细信息活动中了解点击了哪些水果，如下所示：

Intent detailIntent =new Intent(SecondScreen.this, Details.class);          
detailIntent.putExtra("fruitPosition", arg2);
startActivity(detailIntent);

然后在您的详细信息活动中，您将检索该号码并相应地定位ViewPager：

setContentView(R.layout.detail);    
app = ((MyApplication) getApplicationContext());
pager = (ViewPager) findViewById(R.id.pager);
FragmentManager fm = getSupportFragmentManager();      
pagerAdapter = new MyFragmentPagerAdapter(fm,app.totalvalue);   
pager.setAdapter(pagerAdapter);
Intent startIntent = getIntent();
int fruitPosition = startIntent.getIntExtra("fruitPosition", 0);
pager.setCurrentItem(fruitPosition);

项目上的Android列表视图在下一个屏幕中点击进入页面查看器并滑动
