Membuat Browse File pada Android

Pada Android tidak ada komponen semacam Open Dialogh, Oleh karerna itu kita membuat semacam Window(Actyviti) untuk memilih file agar user friendly. Caranya Buat Project Android.

Kemudian pada file main.xml Ubah Sehingga menjadi seperti di bawah ini :
main.xml

Buat satu file layout di folder res/layout dengan nama row.xml:
row.xml

Kemudian pada Activity utama, tambahkan kode program berikut :
MainActivity

package com.jasz.openfiledialog;

public class MainActivity extends ListActivity {

private List<string> item = null;

private String root = "/";
private TextView myPath;

/** Called when the activity is first created. */
@Override

getDir(root);
}

private void getDir(String dirPath) {
myPath.setText("Location: " + dirPath);
item = new ArrayList<string>();
path = new ArrayList<string>();
File f = new File(dirPath);
File[] files = f.listFiles();
if (!dirPath.equals(root))
{
item.add(root);
path.add(root);
item.add("../");
path.add(f.getParent());
}
for (int i = 0; i < files.length; i++)
{
File file = files[i];
path.add(file.getPath());
if (file.isDirectory())
item.add(file.getName() + "/");
else
item.add(file.getName());
}
ArrayAdapter<String> fileList =
new ArrayAdapter<string>(this, R.layout.row, item);
setListAdapter(fileList);
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
File file = new File(path.get(position));
if (file.isDirectory())
{
if (file.canRead())
getDir(path.get(position));
else
{
new AlertDialog.Builder(this)
.setIcon(R.drawable.icon)
.setTitle("[" + file.getName() + "] folder can't be read!")
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).show();
}
}
else
{
new AlertDialog.Builder(this)

.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {

}
}).show();
}
}
}

Jangan lupa, jika ingin dapat mengakses Storage External (SDCARD) tambahkan permission berikut pada AndroidManifest.xml :
