我的交错网格视图适配器在 api 19 或更高版本中正常工作。但是当我在 api 17 或更低版本中运行时，我发现适配器设置不正确。如果我更改它工作正常，它表明我的适配器Staggered Grid View类 Grid View工作正常。但我不知道我的问题在哪里。未在交错网格视图中设置的图像。可能是因为我的视图寻呼机 tis 是我的带有 viewpager 的选项卡视图 XML：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<ir.hisis.cloth.SlidingTabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="2dp"
android:background="@color/ColorPrimary"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="1">
</android.support.v4.view.ViewPager>
</LinearLayout>
这是我的交错网格视图 Xml：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.etsy.android.grid.StaggeredGridView
android:id="@+id/grid_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:item_margin="8dp"
app:column_count="1" />
</FrameLayout>
这是我的主要活动：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setTitle("");
// Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
adapter = new TabsPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);
// Assigning ViewPager View and setting the adapter
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
// Assiging the Sliding Tab Layout View
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width
// Setting Custom Color for the Scroll bar indicator of the Tab View
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
@Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.tabsScrollColor);
}
});
标签页适配器：
public class TabsPagerAdapter extends FragmentStatePagerAdapter {
CharSequence Titles[];
int NumbOfTabs;
public TabsPagerAdapter(FragmentManager fm,CharSequence mTitles[], int mNumbOfTabsumb) {
super(fm);
this.Titles = mTitles;
this.NumbOfTabs = mNumbOfTabsumb;
}
@Override
public Fragment getItem(int position) {
if(position == 0)
{
return new MainFragment();
}
else if(position == 1)
{
return new MainFragment();
}
else
{
return new MainFragment();
}
}
@Override
public CharSequence getPageTitle(int position) {
return Titles[position];
}
@Override
public int getCount() {
return NumbOfTabs;
}
}
