多选列表对话框

 

和单选列表对话框相似，这里需要通过setMultiChoiceItems将array.xml中的数据添加进去。
当单击列表项时会产生Click事件，这里用到的监听器是DialogInterface.OnMultiChoiceClickListener，

具体实现如下：
 第一步：
添加res/values/array.xml的数据
[xhtml] view plaincopy
<?xml version="1.0" encoding="utf-8"?>  
<resources>  
    <string-array name="hobby">  
        <item>篮球</item>  
        <item>足球</item>  
        <item>排球</item>  
    </string-array>  
</resources>  

 
第二步：一个输入框和一个按钮
res/layout/muti_choice_dialog_layout.xml
[xhtml] view plaincopy
<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout  
  xmlns:android="http://schemas.android.com/apk/res/android"  
  android:orientation="vertical"  
  android:layout_width="fill_parent"  
  android:layout_height="wrap_content">  
  <EditText android:id="@+id/editText"  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="这是一个多选列表对话框"  
  />  
  <Button android:id="@+id/button"  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="显示多选列表对话框"  
  />  
</LinearLayout>  

 
第三步：
src/com/dialog/activity/MutiChoiceDialogActivity.java
[java] view plaincopy
package com.dialog.activity;  
  
import android.app.Activity;  
import android.app.AlertDialog;  
import android.app.AlertDialog.Builder;  
import android.app.Dialog;  
import android.content.DialogInterface;  
import android.os.Bundle;  
import android.view.View;  
import android.widget.Button;  
import android.widget.EditText;  
  
public class MutiChoiceDialogActivity extends Activity {  
      
    private final int MUTI_CHOICE_DIALOG = 1;  
      
    boolean[] selected = new boolean[]{false,false,false};  
      
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.muti_choice_dialog_layout);  
          
        Button button = (Button) findViewById(R.id.button);  
        View.OnClickListener listener = new View.OnClickListener() {  
              
            @Override  
            public void onClick(View view) {  
                showDialog(MUTI_CHOICE_DIALOG);  
            }  
        };  
        button.setOnClickListener(listener);  
    }  
      
    @Override  
    protected Dialog onCreateDialog(int id) {  
        Dialog dialog = null;  
        switch(id) {  
            case MUTI_CHOICE_DIALOG:  
                Builder builder = new AlertDialog.Builder(this);  
                builder.setTitle("多选列表对话框");  
                builder.setIcon(R.drawable.basketball);  
                DialogInterface.OnMultiChoiceClickListener mutiListener =   
                    new DialogInterface.OnMultiChoiceClickListener() {  
                          
                        @Override  
                        public void onClick(DialogInterface dialogInterface,   
                                int which, boolean isChecked) {  
                            selected[which] = isChecked;  
                        }  
                    };  
                builder.setMultiChoiceItems(R.array.hobby, selected, mutiListener);  
                DialogInterface.OnClickListener btnListener =   
                    new DialogInterface.OnClickListener() {  
                        @Override  
                        public void onClick(DialogInterface dialogInterface, int which) {  
                            String selectedStr = "";  
                            for(int i=0; i<selected.length; i++) {  
                                if(selected[i] == true) {  
                                    selectedStr = selectedStr + " " +  
                                        getResources().getStringArray(R.array.hobby)[i];  
                                }  
                            }  
                              
                            EditText editText = (EditText) findViewById(R.id.editText);  
                            editText.setText(selectedStr);  
                        }  
                    };  
                builder.setPositiveButton("确定", btnListener);  
                dialog = builder.create();  
                break;  
        }  
        return dialog;  
    }  
}

这个哥自己的代码~

AlertDialog builder = new AlertDialog.Builder(ReviewsActivity.this)
				.setTitle("标签")
				.setMultiChoiceItems(tagStrings, taged,
						new OnMultiChoiceClickListener() {

							@Override
							public void onClick(DialogInterface dialog,
									int which, boolean isChecked) {
								if (isChecked) {
									lv.setItemChecked(which, false);
								}
							}
						})
				.setPositiveButton("确定", new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						if (lv.getCheckedItemCount() <= 0) {
							Toast.makeText(
									ReviewsActivity.this,
									ReviewsActivity.this
											.getString(R.string.tags_null),
									Toast.LENGTH_SHORT).show();
							showTagsItems();
						} else {
							for (int i = 0; i < taged.length; i++) {
								if (lv.getCheckedItemPositions().get(i)) {
									taged[i] = true;
								}
							}
							System.out.println(taged);
						}
					}
				}).setNegativeButton("取消", null).create();
		lv = builder.getListView();
		builder.show();

如果你自己不写取消选中状态的代码~丫就取消不了选中的状态~多他妈的坑爹的设计啊~
