An awesome Android custom load control _android

In the design of applications, we should love minimalism, simple is good, for many users, complex things are not popular.
I want to achieve is according to different situations to show different loading effect, with Tiaogan, the effect is to draw lessons from the effect of a project, I think it is necessary to extract the package to improve the future use. The situation is roughly divided into: loading, no network, no data, loading failure, and so on, these just need a view can be done!

Preview the effect chart:

How do we achieve this?
The layout of the View_loading.xml is as follows:

<?xml version= "1.0" encoding= "Utf-8"?> <framelayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Match_parent "android:layout_height=" match_parent "> <linearlayout android:id= "@+id/lin_loading" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:layout_ gravity= "center" android:visibility= "Gone" android:orientation= "vertical" > <imageview android:id= "@+id/img" _loading "android:layout_width=" 100DP "android:layout_height=" 100DP "android:src=" @drawable/loading_animation "/&

  Gt <textview android:id= "@+id/tv_loading" android:layout_width= wrap_content "android:layout_height=" wrap_content "Android:layout_margintop=" 16DP "android:layout_gravity=" Center_horizontal "android:textsize=" 14sp "/> < /linearlayout> <linearlayout android:id= "@+id/lin_load" android:layout_width= "Wrap_content" Android:layout_ height= "Wrap_content" android:layout_gravity= "Center" android:gravity= "center" android:orientation= "vertical" android:visibility= "visible" > &L T;imageview android:id= "@+id/iv_load" android:layout_width= "100DP" android:layout_height= "100DP" android:src= " @mipmap/ic_launcher "/> <textview android:id= @+id/tv_load" android:layout_width= "Wrap_content" Android: Layout_gravity= "Center_horizontal" android:layout_height= "wrap_content"/> <button android:id= "@+id/btn_lo" Ad "Android:layout_width=" Wrap_content "android:layout_height=" wrap_content "android:layout_margintop=" 8DP "an
 Droid:layout_gravity= "Center_horizontal" android:textsize= "14sp"/> </LinearLayout> </FrameLayout>

From the layout point of view, I divided two parts, one is loaded, the other is with Imagview, text and button layout, someone saw this, will say, wow, this is not very simple? According to the different circumstances to set the value of visibility ah, yes, the principle is this.

The code for Xhloadingview.java is as follows:

Package com.woyou.loadingdemo.widget;

Different processing is done for different situations, and then we call on the activity in need.

 Private Xhloadingview Mloadingview;
  @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
  Setcontentview (R.layout.activity_display);
  Mloadingview = (Xhloadingview) Findviewbyid (r.id.lv_loading); Mloadingview.withloademptytext ("≥﹏≤, what also wood has!"). Withemptyicon (R.drawable.disk_file_no_data).

 .......


 }

Above I was in order to show different effects, so wrote a few click events, the actual is not such, after initialization, in need of the place call OK, the source code comments in detail, you do not have to do too much explanation!
