当跳转到一个需要访问数据的Activity时,显示进度条,给客户友好提示画面(大众点评项目)
方法一
1. XML布局
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<com.handmark.pulltorefresh.library.PullToRefreshListView
android:id="@+id/ptrlv_foot"
android:layout_width="match_parent"
android:layout_height="match_parent">
com.handmark.pulltorefresh.library.PullToRefreshListView>
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center"
android:indeterminateDrawable="@drawable/eatbaozi_anim" />
FrameLayout>
2.Animation布局
android:drawable="@drawable/dropdown_loading_00"
android:gravity="center" />
android:drawable="@drawable/dropdown_loading_01"
android:gravity="center" />
android:drawable="@drawable/dropdown_loading_02"
android:gravity="center" />
3.实现Demo
ProgressBar pBar;
pBar =(ProgressBar) findViewById(R.id.progressBar);
pBar.setVisibility(View.VISIBLE);
//设置进度条隐藏
pBar.setVisibility(View.GONE);
方法二
1.XML与方法一相同
2.Animation布局
android:drawable="@drawable/dropdown_loading_00"
android:duration="200">
android:drawable="@drawable/dropdown_loading_01"
android:duration="200">
android:drawable="@drawable/dropdown_loading_02"
android:duration="200">
3.实现Demo
listBusiness.setEmptyView(ivEmptyView);
((AnimationDrawable)ivEmptyView.getDrawable()).start();
listDistrict =
(ListView) findViewById(R.id.lv_business_district);
listStreet =
(ListView) findViewById(R.id.lv_business_street);
