【问题描述】：

您好，我正在使用没有自定义视图的 AlertDialog，通过以下方式设置列表的数组适配器：

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
final EditText input = new EditText(MainActivity.this);
builder.setView(input);
builder.setTitle("Please Select");

String[] listStrings = "string1", "string2";
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_single_choice, listStrings);
builder.setSingleChoiceItems(arrayAdapter, 0, new DialogInterface.OnClickListener()

    @Override
    public void onClick(DialogInterface dialog, int which)
    
        dialog.dismiss();
    
);

builder.show();

我想附加EditText 用于搜索列表，但EditText 显示在列表末尾。我想要EditText 列表顶部，所以请建议我不要使用自定义布局。

final EditText input = new EditText(MainActivity.this);
builder.setView(input);

我尝试改变builder.setView(input);的顺序

【参考方案1】：

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    final EditText input = new EditText(MainActivity.this);
    LinearLayout layout=new LinearLayout(this);
  layout.setOrientation(LinearLayout.VERTICAL);
    layout.addView(input);
    builder.setTitle("Please Select");

    String[] listStrings = "string1", "string2";
    ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_single_choice, listStrings);

    ListView list=new ListView(this);


    list.setAdapter(arrayAdapter);
    layout.addView(list);
    list.setOnItemClickListener(new OnItemClickListener() 

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) 


        
    );
   builder.setView(layout);
    builder.show();

【参考方案2】：

试试这个

boolean checked = false;


AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        LinearLayout linear = new LinearLayout(MainActivity.this);
        LinearLayout.LayoutParams parm = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        linear.setOrientation(LinearLayout.VERTICAL);
        linear.setLayoutParams(parm);
        final EditText input = new EditText(MainActivity.this);
        builder.setTitle("Please Select");
        linear.addView(input);

        String[] listStrings = "string1", "string2";
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_single_choice, listStrings);
        ListView list=new ListView(this);


        list.setAdapter(arrayAdapter);
        linear.addView(list);

        list.setOnItemClickListener(new AdapterView.OnItemClickListener() 

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) 
                CheckedTextView chk = (CheckedTextView) view;
                Log.d("", "Checked = " + checked);
                checked = checked ? false:true;
                chk.setChecked(checked);

            
        );
        builder.setView(linear);

        builder.show();
