android平台上的图片裁剪,可以获取正方形图片。
使用activity方法:
new Crop(Uri.fromFile( new File(Environment.getExternalStorageDirectory() + "/pic/jjjj.jpg"))) //the picture want to crop .output(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/pic/first.jpg"))) //the file to save crop .withWidth(640) //the max width want to save .start(this);
使用view:
<me.isming.crop.view.CropImageLayout android:id="@+id/clip" android:layout_width="match_parent" android:layout_height="match_parent"/>
效果如如图:
