Android inheritance DialogFragment dialog box 2, androidfragment

Previously I wrote an article about Android inheritance DialogFragment pop-up dialog box 1. This time I modified some things based on the previous one, that is, how to get getDialog () in DialogFragment is to get the handle of the current dialog box. You can perform flexible operations with variable layout. It is used like getactivity. See the code below.

Demo: Click

MainActivity

Package com. example. fragmentdialogdemo; import com. example. fragmentdialogdemo. testDialog. onTestListener; import android. OS. bundle; import android. support. v4.app. fragmentActivity; import android. view. menu; import android. view. view; import android. view. view. onClickListener; import android. widget. button; import android. widget. textView; import android. widget. toast; public class MainActivity extends FragmentActivity implements OnClickListener, onTestListener {private String mstrName = ""; private String mstrHigh = ""; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); initUI ();} private void initUI () {Button buttonTest = (Button) findViewById (R. id. buttonTest); buttonTest. setOnClickListener (this) ;}@ Overridepublic boolean onCreateOptionsMenu (Menu menu) {getMenuInflater (). inflate (R. menu. main, menu); return true;} // interface callback function @ Overridepublic void onTestListener (int uniqueIdentifier, String strName, String strHigh) {if (uniqueIdentifier = 1) {Toast. makeText (getApplicationContext (), "Name:" + strName + ", height:" + strHigh, Toast. LENGTH_LONG ). show (); TextView textView1 = (TextView) findViewById (R. id. textView1); textView1.setText ("name:" + strName + ", height:" + strHigh) ;}mstrname = strName; mstrHigh = strHigh ;}@ Overridepublic void onClick (View arg0) {switch (arg0.getId () {case R. id. buttonTest: // instantiate TestDialog. You can input parameters, such as the title or other parameters, and a unique code. testDialog dialog = new TestDialog (). newInstance ("enter", 1, mstrName, mstrHigh); dialog. show (this. getsuppfrfragmentmanager (), "TestDialog"); break; default: break ;}}}

TestDialog
