Android (5) Wait window, android wait window

I. Wait for window implementation:

Record: sometimes it is necessary to add a waiting window to improve the user experience when downloading data. There are two waiting windows:

The first type of rotating ProgressBar:

Main Interface:

Public class MainActivity extends Activity {private Button button1; private TextView textview1; public AlertDialog selfdialog; private MainActivity main; public Handler mhandler = new Handler () {public void handleMessage (Message msg) {switch (msg. what) {// display TextViewcase 1: Toast. makeText (main, "successful", Toast. LENGTH_SHORT ). show (); textview1.setVisibility (View. VISIBLE); break;} super. handleMessage (msg) ;}}; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); main = this; button1 = (Button) findViewById (R. id. button1); textview1 = (TextView) findViewById (R. id. textview1); button1.setOnClickListener (new View. onClickListener () {@ Overridepublic void onClick (View arg0) {showDialogLoading () ;});} // wait for your void showDialogLoading () {LayoutInflater inflater = (LayoutInflater) this. getSystemService (this. LAYOUT_INFLATER_SERVICE); // viewView view = inflater. inflate (R. layout. footer, null); AlertDialog. builder ad = new AlertDialog. builder (this); selfdialog = ad. create (); selfdialog. setView (view); // block click selfdialog. setCancelable (false); selfdialog. show (); new Thread () {@ Overridepublic void run () {try {Thread. sleep (3000);} catch (InterruptedException e) {e. printStackTrace ();} Message message = new Message (); message. what = 1; main. mhandler. sendMessage (message); // disable dialogselfdialog. dismiss ();}}. start ();}}

Activity_main.xml:

<? Xml version = "1.0" encoding = "UTF-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "wrap_content" android: orientation = "vertical" android: gravity = "center"> <Button android: id = "@ + id/button1" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "Click me"/> <TextView android: id = "@ + id/textview1" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "show me after loading" android: visibility = "gone"/> </LinearLayout>

Footer. xml:

<? Xml version = "1.0" encoding = "UTF-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "wrap_content" android: orientation = "vertical" android: gravity = "center"> <Button android: id = "@ + id/button1" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "Click me"/> <TextView android: id = "@ + id/textview1" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "show me after loading" android: visibility = "gone"/> </LinearLayout>

In this way, the first wait window is implemented.

The second type of progress bar wait window:

Main Interface:

Public class MainActivity extends Activity {private Button button1; private TextView textview1; private TextView textview2; public AlertDialog selfdialog; private MainActivity main; public Handler mhandler = new Handler () {public void handleMessage (Message msg) {switch (msg. what) {// display TextViewcase 1: textview2.setText ("being downloaded (" + msg. obj. toString () + "/10)"); break;} super. handleMessage (msg) ;}}; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); main = this; button1 = (Button) findViewById (R. id. button1); textview1 = (TextView) findViewById (R. id. textview1); button1.setOnClickListener (new View. onClickListener () {@ Overridepublic void onClick (View arg0) {showDialogLoading () ;});} // wait for your void showDialogLoading () {LayoutInflater inflater = (LayoutInflater) this. getSystemService (this. LAYOUT_INFLATER_SERVICE); // viewView view = inflater. inflate (R. layout. footer, null); final ProgressBar progressbar1 = (ProgressBar) view. findViewById (R. id. progressbar1); textview2 = (TextView) view. findViewById (R. id. textview2); AlertDialog. builder ad = new AlertDialog. builder (this); selfdialog = ad. create (); selfdialog. setView (view); // block click selfdialog. setCancelable (false); selfdialog. show (); new Thread () {@ Overridepublic void run () {// getProgress () Get the current progress value // incrementProgressBy () increase each time // getMax () obtain the maximum range of this progress bar int max = progressbar1.getMax (); int I = 0; while (true) {if (I> max) {break;} try {Thread. sleep (1000); progressbar1.incrementProgressBy (1); Message message = new Message (); message. what = 1; message. obj = progressbar1.getProgress (); main. mhandler. sendMessage (message); I ++;} catch (InterruptedException e) {e. printStackTrace () ;}/// disable dialogselfdialog. dismiss ();}}. start ();}}

Footer. xml:

<? Xml version = "1.0" encoding = "UTF-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "wrap_content" android: orientation = "vertical" android: gravity = "center"> <ProgressBar android: id = "@ + id/progressbar1" style = "? Android: attr/progressBarStyleHorizontal "android: layout_width =" 200dip "android: layout_height =" wrap_content "android: max =" 10 "/> <TextView android: id = "@ + id/textview2" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "Download in progress (0/10)" android: textColor = "@ android: color/black" android: textSize = "9sp"/> </LinearLayout>

Activity_main has the same layout as the previous example.
