I was working yesterday and not today. Have two buttons one to go back, one that is an emergency button that calls a method to open the dialer for a call to the ambulance.
I think it may be an XML problem not sure was working fine now unresponsive maybe I changed something I shouldn't have. When it was clicking earlier it was saying the method could not be found which I just don't get it as it is in the correct file

If you plan on using android:onClick="call"in your xml then you should also have a corresponding function called callin your activity and the logic to perform the click goes inside it.
If you plan on extending the View.onClickListener then inside your override void onClick() you can have a switch statement of your button ids and perform your logic
alternatively you can ignore the first two and get the id of the button and implement the click logic inside the onCreate()

I have tow on_click event in one activity linked to tow different buttons but what happened is when I press the first or second button the first on_click event is the one who is working!! here is the java code:
TextView user;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_student_activity);
user=findViewById(R.id.textView);
Intent i = getIntent();
String msg = i.getStringExtra(("msg"));
user.setText("welcome"+" "+msg+" choose a category");
}
public void science(View v){
Intent i = new Intent(this,science_first_activity.class);
startActivity(i);
}
public void art(View v)
{
Intent i = new Intent(this,art_first_activity.class);
startActivity(i);
}
and here is the xml:
<Button
android:id="#+id/button_s"
android:layout_width="258dp"
android:layout_height="65dp"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_marginStart="77dp"
android:layout_marginLeft="77dp"
android:layout_marginEnd="76dp"
android:layout_marginRight="76dp"
android:layout_marginBottom="437dp"
android:onClick="science"
android:text="science" />
<Button
android:id="#+id/button_a"
android:layout_width="258dp"
android:layout_height="65dp"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"

android:layout_marginStart="77dp"

android:layout_marginEnd="76dp"
android:layout_marginRight="76dp"
android:layout_marginBottom="328dp"
android:onClick="art"
android:text="art" />
no matter what button I click he will keep go to the science activity!
Start activity if view id are equal to avoid that.
public void science(View v){
if(view.getId==R.id.button_s){
Intent intentS = new Intent(this,science_first_activity.class);
startActivity(intentS );
}}
public void art(View v)
{
if(view.getId==R.id.button_a){
Intent intentA = new Intent(this,art_first_activity.class);
startActivity(intentA );
}}
In my first activity when i select the text edit the keyboards appears.
When i write one letter the page scrolls as if the edit text had lost focus (but it didn't) and keyboard stay displayed even if it is not there (if i click approximately on the edit text under the displayed keyboard the keyboard entrance animation start again and everything works). I don't know what to do, look's really like a bug to me. Oh and, the bug only appears on this activity (the first activity to start), Android 8.1 Code and screens :
Edit text before bug

Found the solution, it was not related to the code or android. I'm using a Xiomi phone and on the internet it is advised to disable the MIUI Optimisation in the dev options when coding. It was the issue, re-enabling it and rebooting the phone solved the problem. Thanks for the answers !
I am currently making an app where i have a list for request to needs to be marked as finished and another list for the items inside the request. If I select a request, the items inside it will show in the items list and buttons with actions to perform for that items. But when I choose another request and press a button, the text on the button gets cleared. I am using sdk 26 on the project. It seems that the text is not displayed but the text value is still there after I tried to see if the text value of the button is still there.
EDIT:
This is the part where I initialize the views.
btnCustomerInfo = findViewById(R.id.btnCustomerInfo);
btnRemoveDiscount = findViewById(R.id.btnRemoveDiscount);
btnClear = findViewById(R.id.btnClear);
btnPay = findViewById(R.id.btnPay);
btnPrintBill = findViewById(R.id.btnPrintBill);
btnUpdate = findViewById(R.id.btnUpdate);
EDIT:
This is the relevant xml code.

I am not setting any value of button in the onClick
EDIT: Button onClicks
btnCustomerInfo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d(TAG, "btnTxt: "+((Button) view).getText());
showCustomerInfoDlg(ip);
}
});
btnRemoveDiscount.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
MaterialDialog.Builder mDlgBuild = new MaterialDialog.Builder(ctx);
mDlgBuild.title("Discount");
mDlgBuild.content("Remove discount on " + acOr.getTableName() + " " + acOr.getTableNum() + "(" + acOr.getSessionBundle() + ")" + "?");
mDlgBuild.cancelable(false);
mDlgBuild.positiveText("Ok");
mDlgBuild.negativeText("Cancel");
mDlgBuild.onPositive(new MaterialDialog.SingleButtonCallback() {
#Override
public void onClick(#NonNull MaterialDialog dialog, #NonNull DialogAction which) {
dialog.dismiss();
Progress_dialog("Removing discount ...");
progressDlg.show();
}
});
mDlgBuild.onNegative(new MaterialDialog.SingleButtonCallback() {
#Override
public void onClick(#NonNull MaterialDialog dialog, #NonNull DialogAction which) {
dialog.dismiss();
}
});
mDlgBuild.show();
}
});
for btnTransfer:
final MaterialDialog mDlg = new MaterialDialog.Builder(MainActivity.this)
.customView(R.layout.dlg_transfer_table,true)
.cancelable(false)
.negativeText("Cancel")
.onNegative(new MaterialDialog.SingleButtonCallback() {
#Override
public void onClick(#NonNull MaterialDialog dialog, #NonNull DialogAction which) {
dialog.dismiss();
}
}).show();
TextView lblTableNum = (TextView)mDlg.findViewById(R.id.lblDlgTransferTableNumber);
TextView lblCustomerName = (TextView)mDlg.findViewById(R.id.lblDlgTransferCustomerName);
RecyclerView lstTable = (RecyclerView)mDlg.findViewById(R.id.lstDlgTransferTableList);
The other buttons do printing, opens a webview, remove items on the list for the items inside the request, and shows another button. Even if the buttons still doesn't have code in it, clicking it still removes the text on the buttons display.
EDIT: Gif
EDIT: this are the code of the two buttons
Pay button:
final MaterialDialog mDlg = new MaterialDialog.Builder(MainActivity.this)
.title("Payment Options")
.customView(R.layout.dlg_pay_option,true)
.cancelable(false).show();
Button btnCash = (Button)mDlg.findViewById(R.id.btnDlgPayOptionCash);
Button btnCard = (Button)mDlg.findViewById(R.id.btnDlgPayOptionCard);
Button btnOther = (Button)mDlg.findViewById(R.id.btnDlgPayOptionOther);
Button btnCancel = (Button)mDlg.findViewById(R.id.btnDlgPayOptionCancel);
Button btnRemovePayment = (Button)mDlg.findViewById(R.id.btnDlgPayOptionRemovePayment);
btnCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mDlg.dismiss();
}
});
btnCash.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mDlg.dismiss();
typeOfPayment = "cash";
CashPayment();
}
});
btnCard.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mDlg.dismiss();
typeOfPayment = "card";
CardPayment();
}
});
btnOther.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mDlg.dismiss();
typeOfPayment = "other";
OtherPayment();
}
});
Update button:
Intent i = new Intent(MainActivity.this, UpdateOrder.class);
i.putExtra("or_id", acOr.getSessionBundle());
i.putExtra("cust_name", acOr.getCustomerName());
i.putExtra("table_num", acOr.getTableNum());
startActivity(i);
finish();
At first, I already selected an item on the right then clicked pay. Next, I selected another item on the right and clicked pay. Then I clicked cancel on the dialog. Lastly, I clicked the update button.
There's a good chance that the text is not cleared but has the background color in a certain state. To deal with it, you can create a color state list and set it in the android:textColor attribute.
I know this question has been asked many times but hear me out. I have MainActivity which is a LoginActivity & it uses facebook login and AccountKit From Facebook to login and start next activity which is a ContactsActivity. When i am in ContactsActivity and press back button it takes me to MainActivity but i want to close the application as user has successfully logined in and if the user again opens the app it should open ContactsActivity directly as user has signed in successfully previously.
Problem is when i press Back button in Contacts Activity,it takes me to LoginActivity,i already tried finish() after startActivity(intent) which closes my app and not takes me to ContactsActivity after successfull signin.If i open my app again then it takes me directly to ContactsActivity.
I even tried onBackPressed in which i wrote finish but it doesnt work.
In Android Manifest also i wrote android:noHistory="true" in MainActivity tag but it doesn't work.
Please help

In normal way you shouldn't close app - user will moves it to back by pressing home or closing your activities by pressing back.
But you can use this tips:
1) Close old activities after starting the new ones if they not needed in back stack:
startActivity(newActivityIntent);
finish();
The override onBackPressed and the app will close
2) You can move task to back (instead of close) if you need http://developer.android.com/reference/android/app/Activity.html#moveTaskToBack(boolean)
I have 2 activities that involved in this question:
LoginActivity: A Login in Screen (called by a subclass of Activity Class)
Updater Activity: A Update Screen that show updating progress when new app version is availble (called by a subclass of Application Class)
This is what I want:
When the app FIRST LAUNCH, and if new version of the app is available, the UPDATER ACTIVITY should be on top of every activity include the Login Activity,
so it will be the first screen user see during first launch of the app.
only after the updating progress is done, the UPDATER ACTIVITY will be dismissed then Login Screen be on top.
However this is what actually happened:
The LOGIN ACTIVITY always on top of UPDATER ACTIVITY...
My Guess is that since the UPDATER ACTIVITY is called By APPLICATION CLASS's subClass, and the LOGINACTIVITY is called by an ACTIVITY CLASS sub class,
the Application class's method such as OnResume always get called before Activity onCreate Method, thus the LOGINACTIVITY always appear on top of UPDATER ACTIVITY,
I just wondering if there is anyway I could make my UPDATER ACTIVITY be on top of any activities including the LOGIN ACTIVITY?
//LoginActivity involved
public abstract ClassA extends Activity {
.....
.....
protected void onResume() {
super.onResume();
.....
if(isAuthenticated){
Intent intent = new Intent(this, LoginActivity.class)
.putExtra(...)
startActivityForResult(intent, XXX);
}
}
}

super.onCreate();
Intent updaterIntent = new Intent(this, UpdaterActivity.class);
updaterIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
