AlertDialog Builder OnItemSelectedListener

Question

我在AlertDialog生成器上有一个令人讨厌的问题。我想在定制的AlertDialog中处理项目选择，但是OnItemSelectedListener似乎不选择我的点击。

自定义对话框：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="200dp"
android:layout_height="120dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="60dp"
android:background="#AAFFFFFF"
android:orientation="vertical">


<TextView
    android:text="English"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:id="@+id/lang_english"
    android:gravity="center_vertical"
    android:background="@color/borders"
    android:paddingLeft="10dp"
    android:onClick="onLanguageButtonClicked" />
<View
    android:layout_height="1dp"
    android:layout_width="match_parent"
    android:background="#000000" />

<TextView
    android:text="عربى"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:id="@+id/lang_arabic"
    android:gravity="center_vertical"
    android:background="@color/borders"
    android:paddingRight="10dp"
    android:onClick="onLanguageButtonClicked" />

<View
    android:layout_height="1dp"
    android:layout_width="match_parent"
    android:background="#2e2e2e"/>

<TextView
    android:text="کوردی "
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:id="@+id/lang_kurdish"
    android:gravity="center_vertical"
    android:background="@color/borders"
    android:paddingRight="10dp"
    android:onClick="onLanguageButtonClicked" />

</LinearLayout>

在按钮单击我打开对话框并处理它：

public void onClickDrawer(View view) {
    switch (view.getId()) {
        case R.id.button_account_language:
            handleLanguageDialog();
            break;
        case R.id.button_account_currency:
            handleCurrencyDialog();
            break;
        default:
            break;
    }
}

处理人员：

private void handleLanguageDialog() {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setView(R.layout.dialog_language);
    builder.setOnItemSelectedListener(new      AdapterView.
    OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, 
        int position, long id) {
            SharedPreferences preferences =  PreferenceManager
            .getDefaultSharedPreferences(getApplicationContext());
            Log.i("info", "pressed" + Integer.toString(position));
            restartInLocale(new Locale(preferences.getString("locale","")));
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });
    builder.setNegativeButton("CANCEL", new   DialogInterface
    .OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {

        }
        });
    builder.create().show();
}

这是正确的做法还是我遗漏了什么？

提前谢谢你！

我不认为这是正确的方法，你正在使它变得非常复杂。如果我没有错，那么您正在尝试显示语言选择对话框，因此您应该遵循以下步骤。

1. 在strings.xml资源文件中创建字符串数组 英语عربى
2. 当您想要显示警报对话框时，请在下面写代码 私有void handleLanguageDialog() { AlertDialog.Builder builder =新AlertDialog.Builder(getActivity())；builder.setTitle(R.string.pick_color) .setItems(R.array.lang，新DialogInterface.OnClickListener() ){ public DialogInterface.OnClickListener onClick(DialogInterface对话框，int哪个){ //‘哪个“参数包含所选项开关(其中){ case 0:// >的索引位置//；)；返回builder.create()；}

这是在警报对话框中显示语言列表的最简单方法，没有任何正负按钮。

看上去有点不对劲。它应该是这样的：

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater
    LayoutInflater inflater = getActivity().getLayoutInflater();

    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout
    builder.setView(inflater.inflate(R.layout.dialog_signin, null))
        // Add action buttons
       .setPositiveButton(R.string.signin, new DialogInterface.OnClickListener() {
           @Override
           public void onClick(DialogInterface dialog, int id) {
               // sign in the user ...
           }
       })
       .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               LoginDialogFragment.this.getDialog().cancel();
           }
       });
    return builder.create();
}

private void handleLanguageDialog() {
    ArrayList<String> listItems = new ArrayList<>();
    listItems.add("English");
    listItems.add("Arabic");
    new AlertDialog.Builder(this)
            .setTitle("title")
            .setCancelable(false)
            .setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int item) {

                        }
                    }).setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
            // sign in the user ...
        }
    }).setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {

        }
    }).show();
}
