Java – Android eclipse all spinner fonts turn white

In my project, all spinner fonts suddenly turn white, which is why I can't find it They were all black before For example, in the spinner, the drop-down list is all white Its XML file is as follows;

<Spinner
    android:id="@+id/mainactivity_spinner_city"
    android:fontFamily="Roboto"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:layout_below="@+id/mainactivity_imageview_logo"
    android:layout_marginTop="15dp"  />

To ensure that I add #000000 to all relevant locations, but the list is still white Fill the spinner with the following methods:;

ArrayAdapter<String> dataAdapter2 = new ArrayAdapter<String>(context,android.R.layout.simple_spinner_item,list);
    dataAdapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(dataAdapter2);

So I gave simple_ spinner_ Item and simple_ spinner_ dropdown_ Item added black, but it still hasn't changed In the Java section, I didn't do anything about color What are the possible reasons why all these texts turn white?

Edit: only the spinner has a problem I can change the text color of other elements But even if I insert textcolor: "#000000" anywhere related to the spinner, I can't change the spinner

Solution

Found a reason

When I worked with other spinners in other programs, I realized that this strange fact caused the font to turn white Even if the problem looks like a style problem, the root cause lies in the application context In my old code, I filled spinner with the following code;

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),list);

Then I changed the context parameter, as shown below;

ArrayAdapter<String> adapter= new ArrayAdapter<String>(MainActivity.this,list);

Then all the unpopular white fonts turn black!

If getapplicationcontext () is used as a context parameter, some styles may be incorrect Therefore, try hard coding the call context directly, such as youractivity. Com in the adapter This will solve the problem
