43 | mGoogleImage = findViewById(R.id.google_sequence_image); 44 | //设置重复次数 45 | mGoogleImage.setLoopCount(1); 46 | //重复行为默认 根据webp图片循环次数决定 47 | mGoogleImage.setLoopDefault(); 48 | //重复行为无限 49 | mGoogleImage.setLoopInf(); 50 | //重复行为为指定 跟setLoopCount有关 51 | mGoogleImage.setLoopFinite(); 52 | //设置Assets下的图片 53 | mGoogleImage.setImageResourceFromAssets("newyear.webp"); 54 | //设置图片通过drawable 55 | mGoogleImage.setImageResource(R.drawable.newyear); 56 | Uri uri = Uri.parse("file:"+Environment.getExternalStorageDirectory().toString()+"/animation"); 57 | //通过添加"file:"协议，可以展示指定路径的图片，如例子中的本地资源 58 | mGoogleImage.setImageURI(uri); 59 | } 60 | ``` 61 | #### 当然你也可以不使用我这里的AnimatedImageView，AnimatedImageView是我参考其它的代码后修改封装的类，直接使用FrameSequenceDrawable+ImageView也是可以的，使用方法如下 62 | ``` java 63 | ImageView mImage; 64 | InputStream in = null; 65 | in = getResources().getAssets().open("anim.webp"); 66 | final FrameSequenceDrawable drawable = new FrameSequenceDrawable(in); 67 | drawable.setLoopCount(1); 68 | drawable.setLoopBehavior(FrameSequenceDrawable.LOOP_FINITE); 69 | drawable.setOnFinishedListener(new FrameSequenceDrawable.OnFinishedListener() { 70 | @Override 71 | public void onFinished(FrameSequenceDrawable frameSequenceDrawable) { 72 | 73 | } 74 | }); 75 | mImage.setImageDrawable(drawable);
