wish of those help In fact, you didn't set the listener. So you should add changeText() after setContentView(R.layout.activity_my);.

OnClick method on Android Studio is not working
Date : March 29 2020, 07:55 AM
wish helps you I'm trying to show a message using a toast when you click one button. I did one OnClick ethod, but I don't know why is not executing when I click on the button. , You have to initialize your button in your onCreate() something like: @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("OnCreate", "OnCreate method has been executed");
Button b = (Button) findViewById(R.id.yourButtonIdInXML);
b.setOnClickListener(this);
}

onClick function not working in android studio
Date : March 29 2020, 07:55 AM
will be helpful for those in need I was trying to make a timer app and I came across a hurdle. When I try to click the button its not performing its task. The onClick function seems to go wrong somewhere. , You are setting the event handler on TextView not on Button. <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0:30"
android:id="@+id/timerTextView"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:singleLine="true"
android:textSize="70sp"
android:onClick="controlTimer" />

Android Studio OnClick just working once
Date : March 29 2020, 07:55 AM
Hope that helps when I try to push the button it only works once... , I guess what you trying to do is this: public class MainActivity extends AppCompatActivity {
TextView txt;
Button btn;
private int mCounter = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt = (TextView) findViewById(R.id.mytext);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
txt.setText("" + mcounter++);
}
} );

Android studio: Button onClick() not working
Date : March 29 2020, 07:55 AM
will be helpful for those in need You forgot to call the setUserTypeOnButtonClick() method after setContentView() in onCreate().
The setContentView() does make the buttons visible but there is no click listener binding taking place, and hence the buttons don't do anything.
