android - Modify images on the buttons according to the spinner chosen

Question

I'm developing an application for android on accessibility and need to dynamically load the images of the buttons according to a spinner chosen. Attached is a photo application. Most of the photos have a spinner empty. When it is clicked, a list would appear and so were chosen something the spinner, the button images would change. Example: Spinner - Bathroom (Images of possibilities this place) Spinner - Kitchen (Images of possibilities this place).

OBS:I chose not to use imagebutton to be easier to manipulate buttons.!

Code buttons:

 <Button
    android:id="@+id/pic1"
    android:layout_column="2"
    android:layout_columnSpan="3"
    android:layout_gravity="left"
    android:layout_row="2"
    android:drawableBottom="@drawable/pic1"
    android:text="@string/pic1" />

Application

Answer 1

实现一个 OnItemSelectedListener 并使用方法 spinner.setOnItemSelectedListener() 将其附加到您的微调器。

然后，您可以在侦听器的 onItemSelected() 函数中设置图像。

Answer 2

希望这可以帮助

public class myActivity extends Activity implements OnItemSelectedListener {
    int[] images = {R.drawable.image01, R.drawable.image02, R.drawable.image03};
    Spinner spinner;
    Button button;

    ...
    private void setView(){
        button = (Button)findViewById(R.id.button);
        spinner = (Spinner)findViewById(R.id.spinner);
        // Register the listener
        spinner.setOnClickListener(myActivity.this);
    }

    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        // Set the background of the button
        button.setBackgroundResource(images[pos]);
    }

    public void onNothingSelected(AdapterView<?> parent) {
        // Another interface callback
    }
}
