The first time the "edit info" button is pressed nothing happens but the subsequent times it works fine. There are many similar questions and I have red through and tried everything I could with no success.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sharedPrefs = getSharedPreferences(USER_PREFERENCES, MODE_PRIVATE);
//call function to load previous values, no intteraction with button
final Button myButton = findViewById(R.id.button);
myButton.setTag(1);
myButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final int status =(Integer) v.getTag();
if(status == 1) {
myButton.setText(getString(R.string.edit_info));
setEditable(false);
v.setTag(0);
} else {
myButton.setText(getString(R.string.save_info));
setEditable(true);
v.setTag(1);
}
}
});
//proposed solution from other question, see note bellow (*)
myButton.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP && !v.hasFocus()) {
// onClick() is not called when the EditText doesn't have focus,
// onFocusChange() is called instead, which might have a different
// meaning. This condition calls onClick() when click was performed
// but wasn't reported. Condition can be extended for v.isClickable()
// or v.isEnabled() if needed. Returning false means that everything
// else behaves as before.
myButton.performClick();
}
return false;
}
});
}
(*) From this question Matěj Hrazdíra proposes adding OnTouchListner but doing this made the button never toggle back.
Here is activity_main.xml
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="false"
android:focusableInTouchMode="false"
android:text="@string/edit_info" />
From the xml the button has already the text "@string/edit_info"
.
In onCreate()
you set its tag to 1. So the listener will execute:
myButton.setText(getString(R.string.edit_info));
setEditable(false);
v.setTag(0);
So the text does not change.
After that the subsequent clicks will change its text.
I don't know what you want exactly, but if in onCreate()
you set its tag to 0, you will see change from the 1st click.
