推荐答案
您可以这样做:(位于DropDownAnchor上)
you can do it like this: (it's on DropDownAnchor)
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
MenuItem searchItem = menu.findItem(R.id.action_search_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
int searchEditTextId = R.id.search_src_text;
final AutoCompleteTextView searchEditText = (AutoCompleteTextView) searchView.findViewById(searchEditTextId);
final View dropDownAnchor = searchView.findViewById(searchEditText.getDropDownAnchor());
if (dropDownAnchor != null) {
dropDownAnchor.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
@Override
public void onLayoutChange(View v, int left, int top, int right, int bottom,
int oldLeft, int oldTop, int oldRight, int oldBottom) {
// screen width
int screenWidthPixel = ActivitySearchUni.this.getResources().getDisplayMetrics().widthPixels;
searchEditText.setDropDownWidth(screenWidthPixel);
}
});
}
return true;
}
