解决方案

首先，你必须初始化的EditText中的onCreate（），并设置或更改值在积极的按钮点击：

示例： 

 受保护的CharSequence [] _​​options = {水星，金星，大地，火星人，朱庇特，土星，天王星，海王星 };
    保护布尔[] _selections =新的布尔[_options.length]

    保护按钮_optionsButton;
    受保护的EditText inputTemp;

    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
        inputTemp =（EditText上）findViewById（R.id.edittexts）;
        _optionsButton =（按钮）findViewById（R.id.button）;
        _optionsButton.setOnClickListener（新ButtonClickHandler（））;
    }

    公共类ButtonClickHandler实现View.OnClickListener {
        公共无效的onClick（视图查看）{
            的ShowDialog（0）;
        }
    }

    @覆盖
    受保护的对话框onCreateDialog（INT ID）{
        返回
                新AlertDialog.Builder（本）
                        .setTitle（行星）
                        .setMultiChoiceItems（_options，_selections，新DialogSelectionClickHandler（））
                        .setPositiveButton（OK，新DialogBu​​ttonClickHandler（））
                        。创建（）;
    }

    公共类DialogSelectionClickHandler实现DialogInterface.OnMultiChoiceClickListener {
        公共无效的onClick（DialogInterface对话框中，单击诠释，布尔选择）{
            Log.i（ME，_options [点击] +选择：+选择）;
        }
    }


    公共类DialogBu​​ttonClickHandler实现DialogInterface.OnClickListener {
        公共无效的onClick（DialogInterface对话框，点击INT）{
            开关（点击）{
                案例DialogInterface.BUTTON_POSITIVE：
                    inputTemp.setText（）;
                    的for（int i = 0; I＆LT; _options.length;我++）{
                        如果（_selections [I]）{
                            如果（。inputTemp.getText（）的toString（）长度（）大于0）{
                                inputTemp.setText（inputTemp.getText（）的toString（）修剪（）+，+ _选项[I]）;
                            }其他{
                                inputTemp.setText（_options [I]）;
                            }
                        }

                    }
                    打破;
            }
        }
    }

解决方案

First you have to initialize EditText in onCreate() and set or change value at positive button clicked :

Example : 

    protected CharSequence[] _options = {"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune"};
    protected boolean[] _selections = new boolean[_options.length];

    protected Button _optionsButton;
    protected EditText inputTemp;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        inputTemp = (EditText) findViewById(R.id.edittexts);
        _optionsButton = (Button) findViewById(R.id.button);
        _optionsButton.setOnClickListener(new ButtonClickHandler());
    }

    public class ButtonClickHandler implements View.OnClickListener {
        public void onClick(View view) {
            showDialog(0);
        }
    }

    @Override
    protected Dialog onCreateDialog(int id) {
        return
                new AlertDialog.Builder(this)
                        .setTitle("Planets")
                        .setMultiChoiceItems(_options, _selections, new DialogSelectionClickHandler())
                        .setPositiveButton("OK", new DialogButtonClickHandler())
                        .create();
    }

    public class DialogSelectionClickHandler implements DialogInterface.OnMultiChoiceClickListener {
        public void onClick(DialogInterface dialog, int clicked, boolean selected) {
            Log.i("ME", _options[clicked] + " selected: " + selected);
        }
    }


    public class DialogButtonClickHandler implements DialogInterface.OnClickListener {
        public void onClick(DialogInterface dialog, int clicked) {
            switch (clicked) {
                case DialogInterface.BUTTON_POSITIVE:
                    inputTemp.setText("");
                    for (int i = 0; i < _options.length; i++) {
                        if(_selections[i]){
                            if(inputTemp.getText().toString().length()>0){
                                inputTemp.setText(inputTemp.getText().toString().trim()+","+_options[i]);
                            }else{
                                inputTemp.setText(_options[i]);
                            }
                        }

                    }
                    break;
            }
        }
    }
