android AlertDialog的简单使用实例

当你的应用需要显示一个进度条或需要用户对信息进行确认时，可以使用alertdialog来完成。下面来介绍常用的四种alertdialog。

1、普通对话框

package com.example.yk.dialogtest; 
 
import android.content.dialoginterface; 
import android.support.v7.app.alertdialog; 
import android.support.v7.app.appcompatactivity; 
import android.os.bundle; 
import android.widget.toast; 
 
/** 
 * alertdialog普通对话框 
 */ 
public class generaldialogactivity extends appcompatactivity { 
 
  @override 
  protected void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_general_dialog); 
    alertdialog.builder alertdialog = new alertdialog.builder(this) 
        .settitle("操作title")//设置title 
        .setmessage("操作message")//设置要显示的message 
        .setcancelable(false)//表示点击dialog其它部分不能取消(除了“取消”，“确定”按钮) 
        .setpositivebutton("确定", new 
            dialoginterface.onclicklistener() { 
      @override 
      public void onclick(dialoginterface dialoginterface, int i) { 
        toast.maketext(generaldialogactivity.this, "点击了确定", toast.length_short).show(); 
 
      } 
    }).setnegativebutton("取消", new dialoginterface.onclicklistener() { 
      @override 
      public void onclick(dialoginterface dialoginterface, int i) { 
//        dialoginterface.dismiss(); 
      } 
    }); 
    alertdialog.show();//别忘了show 
  } 
} 

2、单选对话框

package com.example.yk.dialogtest; 
 
import android.content.dialoginterface; 
import android.support.v7.app.alertdialog; 
import android.support.v7.app.appcompatactivity; 
import android.os.bundle; 
import android.widget.toast; 
 
/** 
 * 单选对话框 
 */ 
public class singledialogactivity extends appcompatactivity { 
  private string[] items={"java","php","c"}; 
  @override 
  protected void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_single_dialog); 
    alertdialog.builder alertdialog = new alertdialog.builder(this) 
        .settitle("提示title") 
//        .setmessage("提示message")//在需要设置单选对话框的情况下是不能设置message的，否则单选对话框内容会失效 
        .setsinglechoiceitems(items, -1, new dialoginterface.onclicklistener() {//checkeditem=-1表示默认不选中 
          @override 
          public void onclick(dialoginterface dialoginterface, int i) { 
            toast.maketext(singledialogactivity.this, "选中了"+items[i], toast.length_short).show(); 
          } 
        }).setpositivebutton("确定", new dialoginterface.onclicklistener() { 
          @override 
          public void onclick(dialoginterface dialoginterface, int i) { 
 
          } 
        }); 
      alertdialog.show(); 
  } 
} 

3、多选对话框

package com.example.yk.dialogtest; 
 
import android.content.dialoginterface; 
import android.support.v7.app.alertdialog; 
import android.support.v7.app.appcompatactivity; 
import android.os.bundle; 
import android.widget.toast; 
 
/** 
 * 多选对话框 
 */ 
public class multichoicedialogactivity extends appcompatactivity { 
  private string[] items={"java","php","c"}; 
  @override 
  protected void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_multi_choice_dialog); 
    alertdialog.builder alertdialog = new alertdialog.builder(this) 
        .settitle("提示title") 
        .setcancelable(false) 
        .setmultichoiceitems(items, new boolean[]{false, false, false}, new dialoginterface.onmultichoiceclicklistener() { 
 
 
          @override 
          public void onclick(dialoginterface dialoginterface, int i, boolean b) { 
            if(b){ 
              toast.maketext(multichoicedialogactivity.this, "选中了"+items[i], toast.length_short) 
                  .show(); 
            } 
 
          } 
        }) 
        .setpositivebutton("确定", new dialoginterface.onclicklistener() { 
          @override 
          public void onclick(dialoginterface dialoginterface, int i) { 
 
          } 
        }); 
    alertdialog.show(); 
  } 
} 

4、进度条对话框

package com.example.yk.dialogtest; 
 
import android.app.progressdialog; 
import android.os.handler; 
import android.os.message; 
import android.support.v7.app.appcompatactivity; 
import android.os.bundle; 
 
/** 
 * 进度条对话框 
 */ 
public class progressdialogactivity extends appcompatactivity { 
  private progressdialog progressdialog; 
 
  @override 
  protected void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_progress_dialog); 
    progressdialog = new progressdialog(this); 
    progressdialog.settitle("提示title"); 
    progressdialog.setcancelable(true); 
//    progressdialog.setprogressstyle(progressdialog.style_spinner);//旋转进度条，默认风格 
    progressdialog.setprogressstyle(progressdialog.style_horizontal);//横向进度条 
    progressdialog.show(); 
 
  } 
}
