pop up select list for android
提问by Denoteone
I am trying to get away from using 5 buttons when I would like to have one when pressed pops up a window that allows the user to select where they want to go.
当我想在按下时弹出一个窗口，让用户选择他们想去的地方时，我试图避免使用 5 个按钮。
Example: button "Country"
示例：按钮“国家”
<Button
android:id="@+id/countrySelect"
android:layout_width="300px"
android:layout_height="wrap_content"
android:text="@string/backhome"
android:layout_x="8px"
android:layout_y="21px"
>
</Button>
and when pressed it would pop up a list of countrys to select from: Something like-
当按下它时，它会弹出一个可供选择的国家/地区列表：类似-
countrySelect.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view){
//POP UP SELECT MENU WHEN SELECTED START A NEW INTENT
Intent myIntent = new Intent(view.getContext(), ***SELECT MENU CONTROLS***.class);
startActivityForResult(myIntent, 0);
}
});
Sorry this probably is easy fix but I am not having much luck when I researched it.
抱歉，这可能很容易解决，但我在研究它时运气不佳。

You can add spinnerin your layout.xml :
您可以在 layout.xml 中添加微调器：
<Spinner
android:id="@+id/areaspinner"
android:layout_width="150dip"
android:layout_height="40dip"
android:drawSelectorOnTop="true"
android:padding="5dip"
android:paddingLeft="10dip"/>
Now in Activity.java :
现在在 Activity.java 中：
areaspinner = (Spinner) findViewById(R.id.areaspinner);
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, array); //array you are populating
adapter2.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
areaspinner.setAdapter(adapter2);
areaspinner.setSelection(Integer.parseInt(strarea));
Now you can get gtghe selected value from the spinner by :
现在您可以通过以下方式从微调器中获取 gtghe 选定值：
int ipos=areaspinner.getSelectedItemPosition();
String str=array[iPos];
Good luck.
祝你好运。

You could use AlertDialogfor that. It can show a list of items and react when user taps on any of them http://developer.android.com/guide/topics/ui/dialogs.html#AlertDialog
你可以用AlertDialog它。它可以显示项目列表并在用户点击其中任何一个时做出反应http://developer.android.com/guide/topics/ui/dialogs.html#AlertDialog

为什么不使用 Spinner 或 Single selection 警报对话框呢？ http://developer.android.com/guide/topics/ui/dialogs.html#AlertDialog
