How to open one specific folder from the gallery in android?

Question

I use the code below to open the default Android gallery app. It opens all image folders under sdcard. How can I open only one specific folder?

Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); intent.setType("image/*"); startActivityForResult(Intent.createChooser(intent, "Pick any photo"), SELECT_IMAGE_FROM_GALLERY_CONSTANT);

Hi, please use the following code. You will get a specific image of the folder.

the code:

 import java.io.File; import android.app.Activity; import android.content.Intent; import android.media.MediaScannerConnection; import android.media.MediaScannerConnection.MediaScannerConnectionClient; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class SDCARD123Activity extends Activity implements MediaScannerConnectionClient{ public String[] allFiles; private String SCAN_PATH ; private static final String FILE_TYPE="image/*"; private MediaScannerConnection conn; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); File folder = new File("/sdcard/Photo/"); allFiles = folder.list(); // uriAllFiles= new Uri[allFiles.length]; for(int i=0;i<allFiles.length;i++) { Log.d("all file path"+i, allFiles[i]+allFiles.length); } // Uri uri= Uri.fromFile(new File(Environment.getExternalStorageDirectory().toString()+"/yourfoldername/"+allFiles[0])); 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.scanBtn); scanBtn.setOnClickListener(new 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; } } } 

Hope this helps you.
