Android(安卓)动画总结-帧动画

帧动画就不多解释了.

如果需要一进页面就播放帧动画有一点要注意, 如果直接在onCreate方法启动有可能导致缺少后面的帧

两种方法可以避免

在onWindowFocusChanged里面启动

 @Override    public void onWindowFocusChanged(boolean hasFocus) {        super.onWindowFocusChanged(hasFocus);        mFrameAnim.start();    }

addIdleHandler

getMainLooper().myQueue().addIdleHandler(new MessageQueue.IdleHandler() {   @Override    public boolean queueIdle() {        mFrameAnim.start();        return false;    }});

完整代码:

FrameAnimActivity

public class FrameAnimActivity extends AppCompatActivity {    private ImageView mIvFramanim;    private Button mBtnStart;    private Button mBtnStop;    private AnimationDrawable mFrameAnim;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_frame_anim);        mIvFramanim = (ImageView) findViewById(R.id.iv_framanim);        mBtnStart = (Button) findViewById(R.id.btn_start);        mBtnStop = (Button) findViewById(R.id.btn_stop);        mFrameAnim = (AnimationDrawable) mIvFramanim.getBackground();        //另一种进入页面就显示动画解决方法        getMainLooper().myQueue().addIdleHandler(new MessageQueue.IdleHandler() {            @Override            public boolean queueIdle() {                mFrameAnim.start();                return false;            }        });    }    /*    * 如果需要进入页面就立即显示动画需要在onWindowFocusChanged方法调用*/    @Override    public void onWindowFocusChanged(boolean hasFocus) {        super.onWindowFocusChanged(hasFocus);//        mFrameAnim.start();    }    public void onClick(View view) {        switch (view.getId()) {            case R.id.btn_start:                mFrameAnim.start();                break;            case R.id.btn_stop:                mFrameAnim.stop();                break;            default:                break;        }    }    @Override    protected void onPause() {        super.onPause();        mFrameAnim.stop();    }}

xml中指定drawable和duration就可以了, 可以指定多个.

mframe_anim.xml

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="false">    <item        android:drawable="@color/colorAccent"        android:duration="200" />    <item        android:drawable="@color/colorPrimary"        android:duration="200" />    <item        android:drawable="@color/colorPrimaryDark"        android:duration="200" />animation-list>
