I am just a starter in Android. I have an Android code which has a Button. On click of the button, it should Invoke AirPlane mode and then again back to normal mode. Here is my code :
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// load controls
tvStatus = (TextView)findViewById(R.id.tvStatus);
togState = (Button)findViewById(R.id.togState);
// set click event for button
togState.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// check current state first
boolean state = isAirplaneMode();
// toggle the state
toggleAirplaneMode(state);
state = isAirplaneMode();
// toggle the state
toggleAirplaneMode(state);
}
});
}
public void toggleAirplaneMode(boolean state) {
// toggle airplane mode
Settings.System.putInt(this.getContentResolver(),Settings.System.AIRPLANE_MODE_ON, state ? 0 : 1);
// broadcast an intent to inform
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !state);
sendBroadcast(intent);
}
public boolean isAirplaneMode() {
return Settings.System.getInt(this.getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) == 1;
}
}
The problem here is, my phone will go in AirPlane mode and it toggles back also. But this process I cannot stop. Is the problem with the way I handled the OnClick Listener by calling same method (toggleAirplaneMode) twice?
Regards,
This answer contains code necessary to do this. Also make sure you have the WRITE_SETTINGS permission.
Adapted from Controlling Airplane Mode:
// read the airplane mode setting
boolean isEnabled = Settings.System.getInt(
getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) == 1;
// toggle airplane mode
Settings.System.putInt(
getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);
// Post an intent to reload
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !isEnabled);
sendBroadcast(intent);
Replace the onClick method with this:
public void onClick(View v) {
// check current state first
boolean state = isAirplaneMode();
// toggle the state
final Handler handler = new Handler(){
#Override
public void handleMessage(Message msg) {
toggleAirplaneMode(!state);
super.handleMessage(msg);
}
};
Thread th = new Thread() {
#Override
public void run() {
toggleAirplaneMode(!state);
handler.sendEmptyMessage(0);
};
};
th.start();
}
Every time you will click the button, it will toggle the airplaneMode.
If it doesn't work, try removing !
Check this out... This might help..
public class MainActivity extends Activity {
Context context;
private void changeRadioComponentEnabled(Context paramContext, String paramString, boolean paramBoolean1, boolean paramBoolean2)
{
boolean bool = false;
ContentResolver localContentResolver = paramContext.getContentResolver();
int i;
if (!paramBoolean1)
i = 1;
else
i = 0;
Settings.System.putInt(localContentResolver, "airplane_mode_on", i);
Settings.System.putString(paramContext.getContentResolver(), "airplane_mode_radios", paramString);
Intent localIntent = new Intent("android.intent.action.AIRPLANE_MODE");
if (!paramBoolean1)
bool = true;
localIntent.putExtra("state", bool);
paramContext.sendBroadcast(localIntent);
if (!paramBoolean2)
{
if (paramString.indexOf("cell") == 0)
Settings.System.putString(paramContext.getContentResolver(), "airplane_mode_radios", "cell");
}
else
Settings.System.putString(paramContext.getContentResolver(), "airplane_mode_radios", "cell,bluetooth,wifi,nfc");
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.context = this;
((Button)findViewById(R.id.button1)).setOnClickListener(new View.OnClickListener()
{
public void onClick(View paramAnonymousView)
{
MainActivity.this.changeRadioComponentEnabled(MainActivity.this.context, "cell", false, false);
}
});
((Button)findViewById(R.id.button2)).setOnClickListener(new View.OnClickListener()
{
public void onClick(View paramAnonymousView)
{
MainActivity.this.changeRadioComponentEnabled(MainActivity.this.context, "cell", true, false);
}
});
}
I got it finally
I used this in my code
public void onClick(View v) {
// check current state first
boolean state = isAirplaneMode();
// toggle the state
toggleAirplaneMode(state);
state = isAirplaneMode();
// toggle the state
toggleAirplaneMode(state);
ser = new ServiceState();
ser.setState(STATE_IN_SERVICE);
}
And I have declared final int STATE_IN_SERVICE = 0; before OnCreate. And ser is the instance of ServiceState.
Thank you for your replies.

I have a working app using threads in fragments, the thing is I need to change the layout. It's not gonna be a Fragment anymore but a standard Activity.
My big problem is that I don't know exactly where to place what's in "onViewCreated" and "onCreateView" so it's crashing when I call "connect to device" which's placed on "onCreateView". Probably because it's too early or something.

Regarding you error

Maybe add that code in the Activity onResume() lifecykle method instead of onCreate if it need to run more then one time
Move the scanningThread, BluetoothAdapter and LocalBroadcastManager LibCore everything to the 'onCreate()' . The 'onCreateView()' should only have the view = inflater.inflate(R.layout.fragment_home_2, container, false);
The onCreate() only initiate stuff hook up local variables views and set clicklisteners. Like all the one-time-stuff. Going from Fragment to Activity is basically almost the same since they have the same lifecykle methods
Check this nice explanation about the-android-lifecycle-cheat-sheet
I have a simple program that changes the background of activity A from activity B.
When you change the background you need to refresh activity A in order for the background to change, after looking around stackoverflow the easiest way was just to call recreate().
I'm not sure if im calling it wrong or in the wrong area but what ends up happening is it will loop the following error when the app is run and eventually crash-
02-01 13:23:53.358 17302-17302/com.package.www.randomapp E/ViewRootImpl: sendUserActionEvent() mView == null
Here's the code for activity A
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainmenu);
backgroundChanger();
recreate();
}
public void backgroundChanger(){
SharedPreferences sharedGradients = getSharedPreferences("gradientInfo", Context.MODE_PRIVATE);
int backgroundGrad = sharedGradients.getInt("backgroundGradient", 0);
if (backgroundGrad == 0){
MMBackground.setBackgroundResource(R.drawable.blackgreengradiant);
}
if (backgroundGrad == 1){
MMBackground.setBackgroundResource(R.drawable.blueblackgradiant);
}
if (backgroundGrad == 2){
MMBackground.setBackgroundResource(R.drawable.goldblackgradiant);
}
and for Activity B
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_options_menu);
variableHandler();
}
public void variableHandler() {
MainMenuBackgroundBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View v) {
final SharedPreferences[] sharedGradients = {getSharedPreferences("gradientInfo", Context.MODE_PRIVATE)};
final SharedPreferences.Editor[] editor1 = {sharedGradients[0].edit()};
final SharedPreferences[] sharedBoolean = {getSharedPreferences("binaryPoint", Context.MODE_PRIVATE)};
final SharedPreferences.Editor[] editorBinary = {sharedBoolean[0].edit()};
final PopupMenu popup = new PopupMenu(getApplicationContext(), v);
popup.inflate(R.menu.menu_background_gradiant_setter);
popup.show();
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(OptionsMenu.this, "Blue and black gradient", Toast.LENGTH_SHORT).show();
editorBinary[0] = sharedBoolean[0].edit();
editorBinary[0].putInt("binaryPoint", 1);
editor1[0] = sharedGradients[0].edit();
editor1[0].putInt("backgroundGradient", 1);
editor1[0].apply();
return true;
case R.id.item2:
Toast.makeText(OptionsMenu.this, "Gold and black gradient", Toast.LENGTH_SHORT).show();
editorBinary[0] = sharedBoolean[0].edit();
editorBinary[0].putInt("binaryPoint", 1);
editor1[0] = sharedGradients[0].edit();
editor1[0].putInt("backgroundGradient", 2);

}
}
The problem is that you are calling recreate() in the onCreate() method of the Activity without any condition which will create an infinite loop. Keep a variable to track whether the activity is recreated or not.
private static boolean alreadyRecreated = false;
//You can add some extra conditions here if you want.
if(!alreadyRecreated){
recreate();
alreadyRecreated = true;
}
recreate(); will cause your activity to be recreated.
i.e, onCreate gets called. Since, you added recreate(); in onCreate method, it is running into infinite loop and crashing.

In your layout you can add a onClick attribute to each button, say onClick="function", and in your activity you just need to implement a method like this:
public void function(View v) {
switch(v.getId()) {
case R.id.buttonBackspace:
// handle the backspace button
break;
case R.id.xxx:
// handle the button
break;
...
}
}
And for digits, I suggest assign a tag to each digit button in the layout, and do your logic in java based on the tag, instead of the text on the button. Because the text is just a UI, it might change in the future due to other possible requirements.
Want to Do : i want to have an Internet check on Start of An app and if it doesn't finds then on clicking Positive button it should go to setting of wifi & if User ON the wifi then on coming back to App i want the dialog box to be dismiss and Animation start else it again show how the Internet Dialog Box .
What i have done : I have placed the Internet Check Dialog in OnResume() and animation code in OnCreate .
Issue is : on start of my App, when it check Wifi connection ,But it also run all the animation code in Oncreate() in continuity instead of running it only after Internet Connection
OnCreate Code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}
}
OnResume
#Override

if(Utils.isNetworkConnected(this)) {
}else{
showWifiAlert();
}
}
Checking Internet Connection Dialog Box:
private void showWifiAlert(){
new MaterialDialog.Builder(CSPLoginActivity.this)
.content("Unable to validate device as Internet not available")
.title("Alert !")
.positiveText("OK")
.negativeText("Cancel")
.callback(new MaterialDialog.ButtonCallback() {
#Override

finish();
}
#Override
public void onPositive(MaterialDialog dialog) {
dialog.dismiss();
startActivity(new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS));
}
})
.cancelable(false)
.show();
}
Please Help , How to achieve what i want to do .
try replacing the onResume method code as following:
#Override
protected void onResume() {
super.onResume();
if(Utils.isNetworkConnected(this)) {
imgLogo.startAnimation(animTranslate);
}else{
showWifiAlert();
}
}

I want to change the airplanemode at the setted time, that I get from a timepicker.
Then I set the time from the timepicker into a calender from witch I get the time for the alarmmanager.set Method but it doesn't do anything.
I watch all over the internet but I didn't found anything. I found this post on stackoverflow but without answer
(Sorry for my bad english)
Thanks for your answers
I found this in My code toggles airplane mode continuously
/** Code snippet in AirplaneModeService*/
#Override
public void onCreate() {
airplaneModeToggler = new AirplaneModeToggler(this);
Thread mThread = new Thread(null, airplaneModeToggleTask, "AirplaneModeToggleTask");
mThread.start();
}
private Runnable airplaneModeToggleTask = new Runnable() {
#Override
public void run() {
airplaneModeToggler.toggle(null);
AirplaneModeService.this.stopSelf();
}
};
I think you need to do an asynchronous task to d that as you can see up here or in the post I linked you.
Edit: I also found here How can one detect airplane mode on Android? in the answer the way to know if it is activated or not (to do something or not ;) )
/**
* Gets the state of Airplane Mode.
*
* #param context
* #return true if enabled.
*/
private static boolean isAirplaneModeOn(Context context) {
return Settings.System.getInt(context.getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) != 0;
}
And finally I found this http://dustinbreese.blogspot.com.es/2009/04/andoid-controlling-airplane-mode.html where I think there is all you need!
