我希望微调器始终在顶部。唯一改变的是微调器下的内容
在您的活动中创建一个简单的方法来刷新下面的布局Spinner
(将保持不变)。该方法将从OnItemSelectedListener
. Spinner
它会是这样的:
private void changeAdress(int newSelectedAdress) {
// The ImageView and the TextView will be already in the layout
ImageView map = (ImageView) findViewById(R.id.theIdOfTheImage);
// Set the image. You know the current address selected by the user
// (the newSelectedAddress int) so get it from the array/list/database
// where you stored it
// also set the image
}
onItemSelected
从回调中调用上述方法:
yourSpinnerRefference.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
changeAddress(position);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
如果这不是您想要的,请解释。
编辑:制作两个数组来保存您的数据:
int[] images = {R.drawable.imag1, R.drawable.imag2 ..etc...};
//also for the text
String[] text = {"text1", "text2 ...etc...};
然后按照我上面推荐的方法使用这两个数组:
private void changeAdress(int newSelectedAddress) {
((ImageView)findViewById(R.id.mapView1)).setImageResource(images[newSelectedAddress]);
// assing an id to the TextView in your layout and do the same as above.
}
不需要多个ImageView
and TextViews
。
