android获取本地图片路径

获取本地图片路径可以通过以下步骤实现：

1. 获取图片URI

Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

2. 获取查询的字段

String[] projection = {MediaStore.Images.Media.DATA};

3. 查询数据

Cursor cursor = getContentResolver().query(uri, projection, null, null, null);

4. 遍历查询结果，获取图片路径

List<String> paths = new ArrayList<>();
if (cursor != null) {
    while (cursor.moveToNext()) {
        String path = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));
        paths.add(path);
    }
    cursor.close();
}

完整代码如下：

Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
List<String> paths = new ArrayList<>();
if (cursor != null) {
    while (cursor.moveToNext()) {
        String path = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));
        paths.add(path);
    }
    cursor.close();
}

注意：需要在 AndroidManifest.xml 中添加读取外部存储的权限。

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
