copied!<p>Would like to give a work around for this problem.</p> <p>Problem : How to use the same activity as both dialog and full screen based.</p> <p>Solution : </p> <ol> <li>Define your activity in your AndroidManifest.xml with the theme <code>@android:style/Theme.Dialog</code><br></li> <li>In your respective <code>.Java</code> file, check for an <code>intent</code> extra that defines <code>dialog</code> mode. <br></li> <li>If it does not exist, set the <code>Theme</code> to <code>android.R.style.Theme</code>. This is the default <code>theme</code> which is applied if you do not define any theme.</li> </ol> <p>Code :</p> <pre><code>boolean fDialogMode = getIntent().hasExtra("dialog_mode"); if( ! fDialogMode ) { super.setTheme(android.R.style.Theme); } </code></pre> <p>Alternate Solution:</p> <p>A more complex solution is to use <code>AlertDialog</code> as below:</p> <ol> <li>Define a <code>ListAdapter</code> class extended from <code>ArrayAdapter</code>. </li> <li><p>return <code>1</code> in <code>getCount</code> function</p> <pre><code>@Override public int getCount() { return 1; } </code></pre></li> <li><p>In the <code>getView</code> function, <code>inflate</code> the <code>layout</code> of the <code>activity</code> you need and do any customization before returning the <code>view</code>.</p> <pre><code>@Override public View getView( int position, View view, ViewGroup group ) { View v = view; if( v == null ) { v = getSystemService(Context.LAYOUT_INFLATER_SERVICE).inflate( <layout res id>, null ); } ... Do any customization here .... return v; } </code></pre></li> </ol> <p>This is definitely a second choice option by if you are not doing too much processing in the <code>activity</code> <code>class</code> this could be an option.</p> <p>Only reason to consider this solution could be that the logic to show it in a <code>dialog</code> is isolated to the places where it is used as a dialog.</p> <p>Both the options worked for me but for obvious reasons I am taking the first option. :-)</p>
