AlterDialog在Android开发中使用也比较频繁，本文就介绍了AlterDialog的几种对话框使用方式及代码解析。

使用AlerDialog 创建对话框?：

AlertDialog.Builder builder = new AlertDialog.Builder(this);

1.设置简单的对话框

builder.setIcon(R.drawable.icon);         builder.setTitle("你确定要离开吗？");         builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {             public void onClick(DialogInterface dialog, int whichButton) {                 //这里添加点击确定后的逻辑             }         });         builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {             public void onClick(DialogInterface dialog, int whichButton) {                 //这里添加点击确定后的逻辑             }         });         builder.create().show();

2.设置列表对话框

String[] mItems = {"item0","item1","itme2","item3","itme4","item5","item6"}; AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);           builder.setTitle("列表选择框");          builder.setItems(mItems, new DialogInterface.OnClickListener() {              public void onClick(DialogInterface dialog, int which) {                  //点击后弹出窗口选择了第几项              }          });          builder.create().show();

3.设置单选对话框

int mSingleChoiceID = -1;  builder.setIcon(R.drawable.icon);      builder.setTitle("单项选择");      builder.setSingleChoiceItems(mItems, 0, new DialogInterface.OnClickListener() {          public void onClick(DialogInterface dialog, int whichButton) {                  mSingleChoiceID = whichButton;          }      });      builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {          public void onClick(DialogInterface dialog, int whichButton) {              if(mSingleChoiceID > 0) {            //  你选择的是" + mSingleChoiceID;              }          }      });      builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {          public void onClick(DialogInterface dialog, int whichButton) {          }      });     builder.create().show();

4.设置多选对话框

ArrayList <Integer>MultiChoiceID = new ArrayList <Integer>(); builder.setIcon(R.drawable.icon);      builder.setTitle("多项选择");      builder.setMultiChoiceItems(mItems,              new boolean[]{false, false, false, false, false, false, false},              new DialogInterface.OnMultiChoiceClickListener() {                  public void onClick(DialogInterface dialog, int whichButton, boolean isChecked) {                     if(isChecked) {                         MultiChoiceID.add(whichButton);                    //   你选择的为：mItems[whichButton]                    }else {                         MultiChoiceID.remove(whichButton);                     }                   }              });      builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {          public void onClick(DialogInterface dialog, int whichButton) {              String str = "";              int size = MultiChoiceID.size();              for (int i = 0 ;i < size; i++) {            <span style="white-space:pre">	</span>  str+= mItems[MultiChoiceID.get(i)] + ", ";              }          }      });      builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {          public void onClick(DialogInterface dialog, int whichButton) {          }      });     builder.create().show();

5.设置自定义布局对话框

     View view =  LayoutInflater.from(this).inflate(R.layout.custom, null);       builder.setIcon(R.drawable.icon);       builder.setTitle("自定义输入框");       builder.setView(<span style="font-family: 宋体, 'Arial Narrow', arial, serif;">view</span>);       builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {           public void onClick(DialogInterface dialog, int whichButton) {           EditText userName = (EditText) textEntryView.findViewById(R.id.etUserName);           EditText password = (EditText) textEntryView.findViewById(R.id.etPassWord);           // userName.getText().toString()  +  password.getText().toString();           }       });       builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {           public void onClick(DialogInterface dialog, int whichButton) {           }       });     builder.create().show();
