我正在按照本教程http://labs.makemachine.net/2010/03/android-multi-selection-dialogs/进行操作，我希望获得一个警报对话框的选定值，我的edittext可以帮助我，我需要在edittext中获取详细信息

答案 0 :(得分：0)
首先，你必须在onCreate（）中初始化EditText，并在点击的正按钮上设置或更改值：
示例：
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;
}
}
}
