如果在AlertDialog中创建EditText单元后调用一个方法，用于一般用途，不是更流畅吗?

public static void EditTextListPicker(final Activity activity, final EditText EditTextItem, final String SelectTitle, final String[] SelectList) {
    EditTextItem.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(activity);
            builder.setTitle(SelectTitle);
            builder.setItems(SelectList, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialogInterface, int item) {
                    EditTextItem.setText(SelectList[item]);
                }
            });
            builder.create().show();
            return false;
        }
    });
}

根据文档，AlertDialog可以使用三种类型的列表:

传统单选列表 持久的单选列表(单选按钮) 持久的多项选择列表(复选框)

下面我将分别给出一个例子。

传统单选列表

制作传统单选列表的方法是使用setItems。

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose an animal");

// add a list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
builder.setItems(animals, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which) {
            case 0: // horse
            case 1: // cow
            case 2: // camel
            case 3: // sheep
            case 4: // goat
        }
    }
});

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

不需要OK按钮，因为只要用户单击列表项控件，就会返回到OnClickListener。

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose an animal")

// add a list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
builder.setItems(animals) { dialog, which ->
    when (which) {
        0 -> { /* horse */ }
        1 -> { /* cow   */ }
        2 -> { /* camel */ }
        3 -> { /* sheep */ }
        4 -> { /* goat  */ }
    }
}

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

单选按钮列表

单选按钮列表相对于传统列表的优点是用户可以看到当前设置是什么。创建单选按钮列表的方法是使用setSingleChoiceItems。

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose an animal");

// add a radio button list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
int checkedItem = 1; // cow
builder.setSingleChoiceItems(animals, checkedItem, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user checked an item
    }
});

// add OK and Cancel buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user clicked OK
    }
});
builder.setNegativeButton("Cancel", null);

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

我在这里硬编码了选定的项，但您可以在实际项目中使用类成员变量跟踪它。

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose an animal")

// add a radio button list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
val checkedItem = 1 // cow
builder.setSingleChoiceItems(animals, checkedItem) { dialog, which ->
    // user checked an item
}


// add OK and Cancel buttons
builder.setPositiveButton("OK") { dialog, which ->
    // user clicked OK
}
builder.setNegativeButton("Cancel", null)

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

复选框列表

创建复选框列表的方法是使用setMultiChoiceItems。

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose some animals");

// add a checkbox list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
boolean[] checkedItems = {true, false, false, true, false};
builder.setMultiChoiceItems(animals, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
        // user checked or unchecked a box
    }
});

// add OK and Cancel buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user clicked OK
    }
});
builder.setNegativeButton("Cancel", null);

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

在这里，我硬编码了列表中已经检查的项目。更可能的情况是，您希望在ArrayList<Integer>中跟踪它们。有关详细信息，请参阅文档示例。如果您总是希望所有内容都开始时未选中，还可以将选中的项目设置为null。

芬兰湾的科特林版本

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose some animals")

// add a checkbox list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
val checkedItems = booleanArrayOf(true, false, false, true, false)
builder.setMultiChoiceItems(animals, checkedItems) { dialog, which, isChecked ->
    // user checked or unchecked a box
}

// add OK and Cancel buttons
builder.setPositiveButton("OK") { dialog, which ->
    // user clicked OK
}
builder.setNegativeButton("Cancel", null)

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

笔记

For the context in the code above, don't use getApplicationContext() or you will get an IllegalStateException (see here for why). Instead, get a reference to the activity context, such as with this. You can also populate the list items from a database or another source using setAdapter or setCursor or passing in a Cursor or ListAdapter into the setSingleChoiceItems or setMultiChoiceItems. If the list is longer than will fit on the screen then the dialog will automatically scroll it. If you have a really long list, though, I'm guessing that you should probably make a custom dialog with a RecyclerView. To test all of the examples above I just had a simple project with a single button than showed the dialog when clicked: import android.support.v7.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { Context context; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); context = this; } public void showAlertDialogButtonClicked(View view) { // example code to create alert dialog lists goes here } }

Android警报对话框有一个，两个和三个按钮 如何实现自定义AlertDialog视图

您可以使用自定义对话框。

自定义对话框布局。list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <ListView
        android:id="@+id/lv"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"/>
</LinearLayout>

在你的活动中

Dialog dialog = new Dialog(Activity.this);
       dialog.setContentView(R.layout.list)

ListView lv = (ListView ) dialog.findViewById(R.id.lv);
dialog.setCancelable(true);
dialog.setTitle("ListView");
dialog.show();

编辑:

使用alertdialog

String names[] ={"A","B","C","D"};
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater = getLayoutInflater();
View convertView = (View) inflater.inflate(R.layout.custom, null);
alertDialog.setView(convertView);
alertDialog.setTitle("List");
ListView lv = (ListView) convertView.findViewById(R.id.lv);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,names);
lv.setAdapter(adapter);
alertDialog.show();

custom.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

</ListView>

Snap

作为初学者，我建议你登录http://www.mkyong.com/android/android-custom-dialog-example/

我将简要介绍它的基本功能

为对话框和主活动创建一个XML文件 在主活动中所需的位置创建一个android类Dialog对象 根据XML文件添加自定义样式和文本 调用dialog.show()方法。

使用“import android.app.AlertDialog;”导入，然后写入

    String[] items = {"...","...."};             
    AlertDialog.Builder build = new AlertDialog.Builder(context);
    build.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //do stuff....
        }
    }).create().show();

你可以用这样的Alert Dialog创建一个简单的Array。

 val sexArray = arrayOf("Male", "Female")
 val selectedPosition = 0

 AlertDialog.Builder(requireContext())
    .setSingleChoiceItems(sexArray, 0) { dialog, position ->
        val selectedSex = sexArray[position]
    }.show()
