我的应用程序中有按钮,当我单击此按钮时,它会打开一个微调器,但是微调器处于下拉模式,我需要在对话框模式下进行。对于API 11及更高版本,有一个简单的代码可以解决这个问题:
Spinner s1 = new Spinner(this, Spinner.MODE_DIALOG);
但我需要使用一些代码,这些代码也适用于7及更高版本的API。请问有人帮帮我吗?

这就是我的表现:
这里的问题是String [];
DialogInterface.OnClickListener questionDialogListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
// implement the coding for getting the selected item.
arg0.dismiss();
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select Question:");
builder.setItems(questions, questionDialogListener);
AlertDialog dialog = builder.create();
dialog.show();
}

我这样做:
LayoutInflater inflater = context.getLayoutInflater();
final View dlg =inflater.inflate(R.layout.dialog,null);
final AlertDialog d = new AlertDialog.Builder(context)
.setView(dlg)
.setPositiveButton("SAVE",
new Dialog.OnClickListener() {
public void onClick(DialogInterface d, int which) {
//Do nothing here. We override the onclick
}
})
.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//This will close dialog
}
})
.create();
d.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
final Spinner mySpinner = (Spinner)dlg.findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(context,android.R.layout.simple_spinner_item );
//ADD VALUES TO adapter
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mySpinner.setAdapter(adapter);
Button b = d.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
d.dismiss();
//DO SOMETHING
}
});
}
});
d.show();
