Use of the "Android-frame" butterknife

Butterknife can eliminate the steps of control Findviewbyid and improve development efficiency.

Usage:

1. Add Dependencies:

Compile ' com.jakewharton:butterknife:5.1.1 '

2. Use in activity:

 Public classMainactivityextendsappcompatactivity {//use Butterknife to initialize the control (eliminating the use of the Findviewbyid () method, which improves development efficiency)@InjectView (r.id.tv)protectedTextView TV; @InjectView (R.ID.IV)protectedImageView IV; @InjectView (R.ID.BTN)protectedbutton button; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); //Register ButterknifeButterknife.inject ( This); Tv.settext ("Hello TextView");    Iv.setimageresource (R.mipmap.ic_launcher); }    //trigger event in the Click () method when r.id.btn represents a control@OnClick (R.ID.BTN)protected voidClick () {Tv.settext ("Button Clicked"); }}

3. Use in Fragment:

 Public classMainfragmentextendsFragment {//use Butterknife to initialize the control (eliminating the use of the Findviewbyid () method, which improves development efficiency)@InjectView (r.id.tv) TextView TV;    @InjectView (R.ID.IV) ImageView IV;    @InjectView (R.ID.BTN) button button; @Nullable @Override PublicView Oncreateview (layoutinflater inflater, @Nullable viewgroup container, @Nullable Bundle savedinstancestate) { View View= Inflater.inflate (R.layout.activity_main, container,false); //Register Butterknife (use Butterknife in fragment to specify a root View)Butterknife.inject ( This, view); returnview; } @Override Public voidonviewcreated (view view, @Nullable Bundle savedinstancestate) {Tv.settext ("Hello Butterknife");    Iv.setimageresource (R.mipmap.ic_launcher); }    //trigger event in the Click () method when r.id.btn represents a control@OnClick (R.ID.BTN) Public voidClick () {Tv.settext ("Button Clicked"); }}

Note: No matter the method or the control, as long as the annotation butterknife, you can not use private or static decoration!!
