Android：使用目标sdk 24打开图库相册

可以从sdk v24开始在Android Gallery中打开相册吗

我有一个应用程序，可以处理图像并将其保存到外部存储器中的特定唱片集名称下。我想有一个可能性，从应用程序中打开该专辑直接在安卓画廊。有可能做到这一点吗

我可以轻松打开单个文件，但不能打开整个相册：

My

AndroidManifest.xml

...
<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths"/>
</provider>
...

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

我打开特定文件的操作：

打开一个特定的文件就可以了。然而，我无法打开整张专辑。这可能吗？

您可以扫描相册中的图像，并在创建的活动中显示它们，而无需打开相册上的图库

public class MainActivity extends AppCompatActivity implements MediaScannerConnection.MediaScannerConnectionClient {
public String[] allFiles;
private String SCAN_PATH ;
private static final String FILE_TYPE="image/*";

private MediaScannerConnection conn;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.content_main);

    File folder = Environment
            .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES + "/YourAlbumName");
    allFiles = folder.list();
    for(int i=0;i<allFiles.length;i++)
    {
        Log.d("all file path"+i, allFiles[i]+allFiles.length);
    }


    SCAN_PATH=Environment.getExternalStorageDirectory().toString()+"/Photo/"+allFiles[0];
    System.out.println(" SCAN_PATH  " +SCAN_PATH);

    Log.d("SCAN PATH", "Scan Path " + SCAN_PATH);
    Button scanBtn = (Button)findViewById(R.id.button);
    scanBtn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            startScan();
        }});
}
private void startScan()
{
    Log.d("Connected","success"+conn);
    if(conn!=null)
    {
        conn.disconnect();
    }
    conn = new MediaScannerConnection(this,this);
    conn.connect();
}
@Override
public void onMediaScannerConnected() {
    Log.d("onMediaScannerConnected","success"+conn);
    conn.scanFile(SCAN_PATH, FILE_TYPE);
}
@Override
public void onScanCompleted(String path, Uri uri) {
    try {
        Log.d("onScanCompleted",uri + "success"+conn);
        System.out.println("URI " + uri);
        if (uri != null)
        {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(uri);
            startActivity(intent);
        }
    } finally
    {
        conn.disconnect();
        conn = null;
    }

创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.content\u main）；
文件夹=环境
.getExternalStoragePublicDirectory（Environment.DIRECTORY_PICTURES+“/YourAlbumName”）；
allFiles=folder.list（）；
对于（int i=0；iHey，感谢您的回复。是的，这是我的解决方案，以防我无法在gallery中打开相册。但我正在寻找一个明确的答案——我可以在默认的gallery应用程序中打开相册吗。
