android裁剪视频框架,android图像裁剪框架uCrop
第一步先导入依赖
implementation 'com.github.yalantis:ucrop:2.2.1'
implementation 'pub.devrel:easypermissions:1.2.0' //权限库
下面开始上代码
这个是重点 网上很多这里就不解释，可以自己问度娘
/**
* 裁剪图片
*
* @param sourceUri
*/
private void startUCrop(Uri sourceUri) {
UCrop.Options options = new UCrop.Options();
//裁剪后图片保存在文件夹中
Uri destinationUri = Uri.fromFile(new File(FileUtil.checkDirPath(Environment.getExternalStorageDirectory() + "/upload/"), "uCrop.jpg"));
UCrop uCrop = UCrop.of(sourceUri, destinationUri);//第一个参数是裁剪前的uri,第二个参数是裁剪后的uri
options.setAllowedGestures( com.yalantis.ucrop.UCropActivity.SCALE, com.yalantis.ucrop.UCropActivity.ROTATE, com.yalantis.ucrop.UCropActivity.ALL );
//设置隐藏底部容器，默认显示
//options.setHideBottomControls(true);
//设置toolbar颜色
options.setToolbarColor( ActivityCompat.getColor( this, R.color.colorPrimary ) );
//设置状态栏颜色
options.setStatusBarColor( ActivityCompat.getColor( this, R.color.colorPrimary ) );
//是否能调整裁剪框
options.setFreeStyleCropEnabled( true );
uCrop.withOptions( options );
uCrop.start(this);
}
