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();

在芬兰湾的科特林:

fun showListDialog(context: Context){
    // setup alert builder
    val builder = AlertDialog.Builder(context)
    builder.setTitle("Choose an Item")

    // add list items
    val listItems = arrayOf("Item 0","Item 1","Item 2")
    builder.setItems(listItems) { dialog, which ->
        when (which) {
            0 ->{
                Toast.makeText(context,"You Clicked Item 0",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            1->{
                Toast.makeText(context,"You Clicked Item 1",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            2->{
                Toast.makeText(context,"You Clicked Item 2",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
        }
    }

    // create & show alert dialog
    val dialog = builder.create()
    dialog.show()
}

private void AlertDialogue(final List<Animals> animals) {
 final AlertDialog.Builder alertDialog = new AlertDialog.Builder(AdminActivity.this);
 alertDialog.setTitle("Filter by tag");

 final String[] animalsArray = new String[animals.size()];

 for (int i = 0; i < tags.size(); i++) {
  animalsArray[i] = tags.get(i).getanimal();

 }

 final int checkedItem = 0;
 alertDialog.setSingleChoiceItems(animalsArray, checkedItem, new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {

   Log.e(TAG, "onClick: " + animalsArray[which]);

  }
 });


 AlertDialog alert = alertDialog.create();
 alert.setCanceledOnTouchOutside(false);
 alert.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()

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。

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;
        }
    });
}
