除了前面的答案，如果你在获得正确的路径(如AndroZip)有问题，你可以使用这个:

  public String getPath(Uri uri ,ContentResolver contentResolver) {
        String[] projection = {  MediaStore.MediaColumns.DATA};
        Cursor cursor;
        try{
            cursor = contentResolver.query(uri, projection, null, null, null);
        } catch (SecurityException e){
            String path = uri.getPath();
            String result = tryToGetStoragePath(path);
            return  result;
        }
        if(cursor != null) {
            //HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
            //THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
            String filePath = cursor.getString(columnIndex);
            cursor.close();
            return filePath;
        }
        else
            return uri.getPath();               // FOR OI/ASTRO/Dropbox etc
    }

    private String tryToGetStoragePath(String path) {
        int actualPathStart = path.indexOf("//storage");
        String result = path;

        if(actualPathStart!= -1 && actualPathStart< path.length())
            result = path.substring(actualPathStart+1 , path.length());

        return result;
    }

这里有两个关于图像拾取器的有用教程，可下载源代码:

如何创建Android图像拾取器

如何在Android上选择和裁剪图像

但是，应用程序有时会被迫关闭，你可以通过添加android:configChanges属性到Manifest文件中的主活动来修复它:

<activity android:name=".MainActivity"
                  android:label="@string/app_name" android:configChanges="keyboardHidden|orientation" >

似乎相机API失去了对方向的控制，所以这将有助于它。：）

假设在SD卡目录中有一个图像文件夹仅用于图像。

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
// tells your intent to get the contents
// opens the URI for your image directory on your sdcard
intent.setType("file:///sdcard/image/*"); 
startActivityForResult(intent, 1);

然后，您可以决定如何处理活动中的内容。

这是一个检索图像路径名称的示例，用您的代码进行测试，以确保您可以处理返回的结果。您可以根据需要更改代码以更好地满足您的需求。

protected final void onActivityResult(final int requestCode, final int
                     resultCode, final Intent i) {
    super.onActivityResult(requestCode, resultCode, i);

  // this matches the request code in the above call
  if (requestCode == 1) {
      Uri _uri = i.getData();

    // this will be null if no image was selected...
    if (_uri != null) {
      // now we get the path to the image file
     cursor = getContentResolver().query(_uri, null,
                                      null, null, null);
     cursor.moveToFirst();
     String imageFilePath = cursor.getString(0);
     cursor.close();
     }
   }

我的建议是尽量让检索图像工作正确，我认为问题是在存储卡上访问图像的内容。看一下在sd卡上显示图像。

如果您能够启动并运行它(可能通过示例提供正确的提供程序)，那么您应该能够为您的代码找到一种变通方法。

通过更新这个问题来让我了解你的进展。祝你好运

public class BrowsePictureActivity extends Activity {

    // this is the action code we use in our intent, 
    // this way we know we're looking at the response from our own action
    private static final int SELECT_PICTURE = 1;

    private String selectedImagePath;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ((Button) findViewById(R.id.Button01))
                .setOnClickListener(new OnClickListener() {

                    public void onClick(View arg0) {

                        // in onCreate or any event where your want the user to
                        // select a file
                        Intent intent = new Intent();
                        intent.setType("image/*");
                        intent.setAction(Intent.ACTION_GET_CONTENT);
                        startActivityForResult(Intent.createChooser(intent,
                                "Select Picture"), SELECT_PICTURE);
                    }
                });
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                Uri selectedImageUri = data.getData();
                selectedImagePath = getPath(selectedImageUri);
            }
        }
    }

    /**
     * helper to retrieve the path of an image URI
     */
    public String getPath(Uri uri) {
            // just some safety built in 
            if( uri == null ) {
                // TODO perform some logging or show user feedback
                return null;
            }
            // try to retrieve the image from the media store first
            // this will only work for images selected from gallery
            String[] projection = { MediaStore.Images.Media.DATA };
            Cursor cursor = managedQuery(uri, projection, null, null, null);
            if( cursor != null ){
                int column_index = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                cursor.moveToFirst();
                return cursor.getString(column_index);
            }
            // this is our fallback here
            return uri.getPath();
    }

}

要显示图像和视频，请尝试以下方法:

    Intent intent = new Intent();
    intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, 1);
    startActivityForResult(Intent.createChooser(intent,"Wybierz plik"), SELECT_FILE);

在上面代码的基础上，我反映了如下代码，可能它更适合:

public String getPath(Uri uri) {
    String selectedImagePath;
    //1:MEDIA GALLERY --- query from MediaStore.Images.Media.DATA
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    if(cursor != null){
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        selectedImagePath = cursor.getString(column_index);
    }else{
        selectedImagePath = null;
    }

    if(selectedImagePath == null){
        //2:OI FILE Manager --- call method: uri.getPath()
        selectedImagePath = uri.getPath();
    }
    return selectedImagePath;
}
