安卓 图片裁剪

[wang823671429]

图片可以移动放缩小 裁剪框也随着放大缩小 裁剪框可以触摸四个顶点放大缩小和移动

以前自己做的，找个按钮调用startPhotoZoom方法即可

	/**
	 * 调用系统裁剪功能
	 */
	public void startPhotoZoom(Bitmap bitmap, int requestCode) {
		String str = MediaStore.Images.Media.insertImage(getContentResolver(),
				bitmap, null, null);
		Intent intent = new Intent("com.android.camera.action.CROP");
		if (TextUtils.isEmpty(str)) {// 大神酷派
			File file = getBitMapFile(bitmap);
			str = file.getPath();
			intent.setDataAndType(Uri.fromFile(file), "image/*");
		} else {
			Uri uri = Uri.parse(str);
			intent.setDataAndType(uri, "image/*");
		}
		// crop为true是设置在开启的intent中设置显示的view可以剪裁
		intent.putExtra("crop", "true");
		// aspectX aspectY 是宽高的比例
		intent.putExtra("aspectX", 1);
		intent.putExtra("aspectY", 1);
		// outputX,outputY 是剪裁图片的宽高
		intent.putExtra("outputX", 120);
		intent.putExtra("outputY", 120);
		intent.putExtra("return-data", true);
		intent.putExtra("noFaceDetection", true);
		startActivityForResult(intent, requestCode);
	}
	/**
	 * BitMap转File
	 */
	private File getBitMapFile(Bitmap bitmap) {
		File file;
		try {
			Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(
					getContentResolver(), bitmap, null, null));
			String[] proj = { MediaStore.Images.Media.DATA };
			Cursor actualimagecursor = managedQuery(uri,
					proj, null, null, null);
			int actual_image_column_index = actualimagecursor
					.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
			actualimagecursor.moveToFirst();
			String img_path = actualimagecursor
					.getString(actual_image_column_index);
			file = new File(img_path);
		} catch (Exception e) {

			openFile.mkdirs();// 尝试创建系统默相册文件夹

		}
		return file;
	}
	/**

	 **/
	private String getCurrentTime() {
		SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd_HHmmss");
		String str = format.format(new Date());
		return str;

	}
	/**
