android textview not changing the text
<p>i got a textview which should changes the text after the intent (directorypicker) finish.that doesn't work.
heres the code:</p>

<pre><code>text = (TextView) findViewById(R.id.choose3);
        text.setText(globalconstant.path);
</code></pre>

<p>should change the text when the intent returns the path:</p>

<pre><code>private void addListenerOnButton() {
        choose_button = (Button) findViewById(R.id.button1);
        choose_button.setEnabled(true);
        choose_button.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {
                // DirectoryPicker.START_DIR = "/mnt/";
                Intent intent = new Intent(settings.this, DirectoryPicker.class);
                startActivityForResult(intent, DirectoryPicker.PICK_DIRECTORY);
                // text.setText(globalconstant.path);
                text = (TextView) findViewById(R.id.choose3);
                text.setText(globalconstant.path);
                ;

            }
