null !animationDrawable.isRunning()) { animationDrawable.start(); } break; case R.id.stop: if (animationDrawable ! null animationDrawable.isRunning()) { animationDrawable.stop(); } break; default: break; } } } 二、通过代码实现帧动画 [java] view plain copy /** * 通过代码添加帧动画方法 */ private void setSrc2FrameAnim() { animationDrawable new AnimationDrawable(); // 为AnimationDrawable添加动画帧 animationDrawable.addFrame( getResources().getDrawable(R.drawable.img00), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img01), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img02), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img03), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img04), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img05), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img06), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img07), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img08), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img09), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img10), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img11), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img12), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img13), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img14), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img15), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img16), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img17), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img18), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img19), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img20), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img21), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img22), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img23), 50); animationDrawable.addFrame( getResources().getDrawable(R.drawable.img24), 50); // 设置为循环播放 animationDrawable.setOneShot(false); imageView.setBackground(animationDrawable); } 点击下载源码 转载于:https://www.cnblogs.com/Im-Victor/p/8760379.html
