使用android调用系统图片(剪切)功能

private Intent formatBmIntent(Bitmap bm) {
//		Intent intent = new Intent("com.android.camera.action.CROP");
		// 在本地选择图片进行剪切
		Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
		intent.setType("image/*");
//		intent.putExtra("data", bm);
		intent.putExtra("crop", "true");
		intent.putExtra("aspectX", 1);
		intent.putExtra("aspectY", 1);
		intent.putExtra("outputX", 200);
		intent.putExtra("outputY", 200);
		intent.putExtra("return-data", true);
		return intent;
	}

 

/** 获取系统剪切图片的Intent */

		intent.putExtra("aspectY", 1);
		intent.putExtra("outputX", outputX);
		intent.putExtra("outputY", outputY);
		intent.putExtra("return-data", true);
		return intent;
	}
