    <p>Alright, so I'm trying to make a file choice dialog, and I got it so I can choose the file, but I want it so when I choose a directory it moves and lists all the files in the new directory. Right now it just goes to a black screen when I hit a directory. How do I make it list the directory's files when I hit a directory? This is the code I got so far:</p> <pre><code>private void loadFileList(){ try{ dir.mkdirs(); } catch(SecurityException e){ Log.e("Error: ", "unable to write on the sd card " + e.toString()); } if(dir.exists()){ mFileList = dir.list(); } else{ mFileList= new String[0]; } } protected Dialog onCreateDialog(int id){ Dialog dialog = null; AlertDialog.Builder builder = new Builder(this); switch(id){ case DIALOG_LOAD_ROM: builder.setTitle("Choose your rom"); if(mFileList == null){ dialog = builder.create(); return dialog; } builder.setItems(dir.list(), new DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialog, int which){ mChosenFile = dir.list()[which]; rom = new File(dir, mChosenFile); if(rom.isDirectory()){ Log.e("log:",dir.getAbsolutePath()); dir = new File(dir, mChosenFile); Log.e("log:",dir.getAbsolutePath()); loadFileList(); showDialog(DIALOG_LOAD_ROM); } else{ loadFileList(); showDialog(DIALOG_LOAD_PATCH); } } }); break; case DIALOG_LOAD_PATCH: builder.setTitle("Choose your patch"); if(mFileList == null){ dialog = builder.create(); return dialog; } builder.setItems(dir.list(), new DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialog, int which){ mChosenFile = dir.list()[which]; File sdcard = Environment.getExternalStorageDirectory(); patch = new File(sdcard, mChosenFile); AlertDialog.Builder alert = new AlertDialog.Builder(masterApp); alert.setTitle("New Rom Name"); alert.setMessage("Please input a name"); // Set an EditText view to get user input final EditText input = new EditText(masterApp); alert.setView(input); alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { String value = input.getText().toString(); File sdcard = Environment.getExternalStorageDirectory(); File newRom = new File(sdcard,value); patchROM(rom, patch, newRom); AlertDialog.Builder alert2 = new AlertDialog.Builder(masterApp); alert2.setTitle("Finished"); alert2.setMessage("Rom has been patched"); alert2.setPositiveButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { System.exit(0); } }); alert2.show(); } }); alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { File sdcard = Environment.getExternalStorageDirectory(); File newRom = new File(sdcard,"newrom.gb"); patchROM(rom, patch, newRom); AlertDialog.Builder alert2 = new AlertDialog.Builder(masterApp); alert2.setTitle("Finished"); alert2.setMessage("Rom has been patched"); alert2.setPositiveButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { System.exit(0); } }); alert2.show(); } }); alert.show(); } }); break; } dialog = builder.show(); return dialog; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
