尝试制作一个弹出一个新的小屏幕的微调器,用户可以从中选择,而不仅仅是下拉菜单。我一直在寻找,所有“基本”的旋转器示例似乎都完成了弹出式旋转器,但对于我的生活,我无法在我的机器上完成它。
我有什么:http://developer.android.com/guide/topics/ui/controls/spinner.html
我想要的是什么:http://www.mkyong.com/android/android-spinner-drop-down-list-example/
我会发布实际的照片,但我没有这样做的声誉点......
//@SuppressLint("ParserError")
public class Timer_appActivity extends Activity implements OnClickListener {
private static final String TAG = "TimerActivity";
//find view and assign to Java variable
EditText Hr;
EditText Min;
EditText Sec;
Button buttonGo;
Button buttonReset;
Spinner mySpinner;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main2);
//find views
mySpinner = (Spinner) findViewById(R.id.playlistSpinner);
//get the names of the playlists on device
List<String> list = new ArrayList<String>();
String[] proj = {MediaStore.Audio.Playlists.NAME};
Cursor myCursor = getContentResolver().query(Uri.parse("content://com.google.android.music.MusicContent/playlists"), proj, null, null, null);
if (myCursor.getCount() > 0) {
myCursor.moveToFirst();
do {
list.add(myCursor.getString(0));
} while (myCursor.moveToNext());
}
myCursor.close();
//define spinner adapter with nice spacing and playlist names
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.row, R.id.playlistNames, list);
//populate adapter with playlist names
mySpinner.setAdapter(adapter);
//add listener to buttons
//buttonGo.setOnClickListener(this);
//buttonReset.setOnClickListener(this);
}
}
和row.xml看起来像:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id = "@+id/linearlayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:id="@+id/playlistNames"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize = "25dp"
android:paddingLeft="5dp"
android:paddingTop="5dp"
android:paddingRight="5dp"
android:paddingBottom="5dp"
/>
</LinearLayout>
和main2的xml看起来像:(微调器的位是最后一个条目)
<?xml version="1.0" encoding="utf-8"?>

android:layout_marginLeft="20dp"
android:layout_marginRight="15dp"
android:layout_marginTop="30dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id = "@+id/HoursLabel"
android:text = "@string/stringHours"
android:layout_column = "1"
android:textSize="30dp"
android:gravity = "center"

答案 0 :(得分:4)
知道了。超级简单。
将以下内容添加到xml文件中微调器的属性列表中。
机器人:spinnerMode = “对话框”
其他选项是
机器人:spinnerMode = “下拉菜单”
这适用于11级及以上,我相信......(也许更低?)
这么容易......伙计
