How to restart Handler after changing data value?

How to restart Handler after changing data value? - java

Good morning StackOverFlow i'm having some issues with Handler i'm trying to start in the MainActivity my Client.java after 50 seconds and also send the message and stop the client and that's work but i have to reopen the connection on every change of ip_txt or term_txt in settings.java
(data is saved from a EditText to DB by clicking on a button )
here is my MainActivity :
public class MainActivity extends AppCompatActivity {
Server server;
Client client;
Handler handler = new Handler();
Runnable runnable = new Runnable() {
#Override
public void run() {
new ConnectTask().execute("");
if (client != null) {
client.sendMessage("IP#" + ipp + " " + "N#" + trm);
}
if (client != null) {
client.stopClient();
}
}
};
settings Settings;
public static TextView terminale, indr, msg;
TextView log;
String ipp,trm;
DataBaseHandler myDB;
allert Allert;
SharedPreferences prefs;
String s1 = "GAB Tamagnini SRL © 2017 \n" +

Here is my settings.java:

indr = (TextView) findViewById(R.id.ipp);
ip_txt = (EditText) findViewById(R.id.ip);
term_txt = (EditText) findViewById(R.id.nTermin);
save = (Button) findViewById(R.id.save);
Cursor cursor = myDB.fetchData();
if(cursor.moveToFirst()){
do {
ip_txt.setText(cursor.getString(1));
term_txt.setText(cursor.getString(2));
}while(cursor.moveToNext());
}
cursor.close();
AddData();
home.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
ipp = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
indr.setText(ipp);
}
public void AddData() {
save.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
myDB.insertData(ip_txt.getText().toString(),
term_txt.getText().toString());
MainActivity.indr.setText(ip_txt.getText().toString());
MainActivity.terminale.setText(term_txt.getText().toString());
Client.SERVER_IP = ip_txt.getText().toString();
finish();
}
}
);
}
}
( If I did not explain it i want to start the handler on the start of the app and also to start it again or immediatly after i change the data in EditText ip_txt or in EditText term_txt )

I would create Variables to store the handler and the runnable, then when you want to restart it just use:
yourHandler.removeCallback(yourRunnable);
yourHandler.postDelayed(yourRunnable,time);
and to start it, just do it as you did,
yourHandler.postDelayed(yourRunnable,5000);
Hope is what you are looking for.
How to create them:
public class ClassName{
Handler yourHandler = new Handler();
Runnable yourRunnable = new Runnable(){
#Override
public void run() {
//yourCode
}
};
// Rest of class code
}
Is just same as you did in your code but in a variable.

Multiple layout setVisibility wont show correct layout after getting pressed on certain layout

I have a layout in which there are several other layouts by including in XML, I add some textviews as buttons to change the view layouts from one layout to another.
I display each layout with the setVisibility method between layouts, with setOnClickListener in the textview.
The problem is just after finishing displaying the "profile" layout and trying to display the "about us" layout, the system displays a "profile" layout instead of the "about us" layout.
Here is myJava
public class SettingMenu extends AppCompatActivity {
View userProfile, settingLayout, userFavorite, UserEditProfile, aboutUS, contactUS, ProgressBar;

solved by using setContentView rather than setVisibility.

save url when re rotate screen from landscape to protrit

I'm trying to play video on player and the video is url that I fetch from an api
so I have a channels in recycleview1 and when I click on one channel the channel start play in new activity
in that activity the player take half of screen and the rest is for recycleview2 which contain some channels for easy and fast navigate between channels
so when I open the channel from recycleview1 and it start playing then I rotate the screen to landscape it work fine then restore the screen to portrate again the channel still working
but the problem is when I click on channel from recycleview2 which lead to update the url that already played and start the new one
so each time I click on channel from recycleview2 the videoview updated to new channel url that clicked
I face problem when I rotate the screen after played channel from recycleview2 the videoview start play a channel that I clicked from recyclewview1 before clicking on new channel from recycleview2 because it return to onCreate method which build the url depend on the information passed with on click
so I used to save the instance state of url so when I rotate the screen to landscape the vidoeview still played the last channel that played
but the problem is when I re rotate the screen to portrate again the videoview here return to the first channel played when start the activity
I tried to save instance state too but it doesn't working

}
you can see that I use:
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
}
else{
}
to set content view for portrait and landscape
and inside else this is the code that I use to save the url in landscape mode:
if (savedInstanceState != null){
myBoolean = savedInstanceState.getString("video");
Toast.makeText(this, "This is my Toast message!",
Toast.LENGTH_LONG).show();
videoView.setVideoURI(Uri.parse(myBoolean));
}
else {
String host = "http://ip/";
String app = mChannelApp;
String streamname = mChannelStreamname;
String playlist = "playlist.m3u8";
vidUri = Uri.parse(host).buildUpon()
.appendPath(app)
.appendPath(streamname)
.appendPath(playlist)
.build();
videoView.setVideoURI(vidUri);
}
and if savedInstanceState null so build url like this from on click information that I pass in portrait mode:
channelObject = getIntent().getParcelableExtra("TVChannel");
if (channelObject != null) {
mChannelTitle = String.valueOf(channelObject.getTitle());
mChannelApp = String.valueOf(channelObject.getApp());
mChannelStreamname = String.valueOf(channelObject.getStreamName());
mChannelCat = String.valueOf(channelObject.getCat());
}
how can I save the url channel when I re rotate screen from landscape to portrait mode again?

App is not responding after running this activity

New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

Just use

and remove finish()

Call number when click list view item

You can write and apply below mentioned steps (Please ignore any syntactical error, I am giving you simple logical steps).
step 1 - Make a global application level loginObject setter and getter like below. Make sure to define Application class in your manifest just like you do it for your LoginActivity
public class ApplicationClass extends Application{
private LoginBean loginObject;
public void setLoginBean(LoginBean object) {
this.loginObject = object;
}
public LoginBean getName() {
return this.loginObject
}
}
Step - 2 Get an instance of ApplicationClass object reference in LoginActivity to set this global loginObject
e.g. setLogin object in your current Loginactivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
appObject.setLoginBean(loginObject)
}
Step - 3 Get an instance of ApplicationClass object reference in any other Activity get this global loginObject where you need to access this login data.
e.g. getLogin object in your otherActivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
LoginBean loginObject = appObject.getLoginBean();
}
