//1:导入依赖

compile 'com.facebook.fresco:fresco:0.11.0'compile 'com.facebook.fresco:animated-gif:0.12.0'

//2:创建MyApplication类继承Application

public class MyApplication extends Application {    @Override    public void onCreate() {        super.onCreate();        Fresco.initialize(this);    }}

//布局文件activity_main中

<com.facebook.drawee.view.SimpleDraweeView    android:layout_width="match_parent"    android:layout_height="500dp"    android:id="@+id/main_simple_drawee_view"    fresco:placeholderImage="@mipmap/ic_launcher"/>

//主函数中调用

public class MainActivity extends AppCompatActivity {    private SimpleDraweeView sdv;    Button btn;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        sdv = (SimpleDraweeView) findViewById(R.id.main_simple_drawee_view);        btn = (Button) findViewById(R.id.btn);        Uri uri =  Uri.parse("http://dynamic-image.yesky.com/740x-/uploadImages/2015/163/50/690V3VHW0P77.jpg");//        sdv.setImageURI(uri);        DraweeController controller = Fresco.newDraweeControllerBuilder()                .setUri(uri)                .setAutoPlayAnimations(true)                .build();        sdv.setController(controller);        btn.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Intent intent = new Intent(MainActivity.this,Main2Activity.class);                startActivity(intent);            }        });    }}
