Android基础之Dialog，通用属性设置

通用属性设置

设置对话框的标题内容等

 //创建对话框，使用对话框构建器alertdialog.builder
  alertdialog.builder builder = new alertdialog.builder(mainactivity.this);
  //设置标题
  builder.settitle("标题");
  //设置对话框的图标
  builder.seticon(r.drawable.header);
  //设置内容
  builder.setmessage("内容");

设置确定取消按钮

 //设置确定按钮
  builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
 // todo auto-generated method stub
}
  });
  //设置取消按钮
  builder.setnegativebutton("取消", new dialoginterface.onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
 // todo auto-generated method stub
}
  });

设置对话框显示与隐藏

  dialog = builder.create();
  //显示对话框
  dialog.show();
  //隐藏对话框
  dialog.dismiss();

设置点击按钮后不关闭对话框

field field = dialog.getclass().getsuperclass()
.getdeclaredfield("mshowing");
  field.setaccessible(true);
  //设置dialog显示/不显示
  field.set(dialog, true/false);

单选对话框

  //不能设置内容，否则单选效果无法展示
  //builder.setmessage("内容");
  //设置单选按钮
  string items1[] = new string[] { "魏", "蜀", "吴" };
  builder.setsinglechoiceitems(items1, 1, new dialoginterface.onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
 // todo auto-generated method stub
 toast.maketext(main3activity.this,which+"",toast.length_long).show();
}
  });

多选对话框

  string item_id2[] = new string[]{"魏", "蜀", "吴"};
  boolean checkeditems[] = {true, false, true};
  builder.setmultichoiceitems(item_id2, checkeditems, new dialoginterface.onmultichoiceclicklistener() {
@override
public void onclick(dialoginterface dialog, int which,
  boolean ischecked) {
 // todo auto-generated method stub
}
  });

进度对话框

**在android8.0以后使用progressbar代替progressdialog**

自定义view的对话框

  view view = view.inflate(main3activity.this, r.layout.item_dialog, null);
  final alertdialog.builder dialog = new alertdialog.builder(main3activity.this);
  dialog.settitle("用户登录：")
 .seticon(r.mipmap.ic_launcher)
 .setview(view)
 .setpositivebutton("ok", new dialoginterface.onclicklistener() {
  @override
  public void onclick(dialoginterface dialoginterface, int i) {
toast.maketext(getapplicationcontext(), "登录成功", toast.length_short).show();
  }
 })

自定义view和位置的对话框

  view view = view.inflate(main3activity.this, r.layout.item_dialog, null);
  dialog dialog = new dialog(main3activity.this);
  //r.layout 后面跟的文件就是加载的自定义布局
  dialog.setcontentview(view);
  window mwindow = dialog.getwindow();
  mwindow.setgravity(gravity.left + gravity.top);
  windowmanager.layoutparams lp = mwindow.getattributes();
  lp.x = 0;
  lp.y = 0;
  lp.width = viewgroup.layoutparams.match_parent;
  lp.height = viewgroup.layoutparams.match_parent;
  mwindow.setattributes(lp);
  dialog.create();
  dialog.show();

日期和时间对话框

//日期对话框
datepickerdialog dialog_date = new datepickerdialog(mainactivity.this);
 dialog_date.settitle("选择日期：");
 dialog_date.seticon(r.mipmap.ic_launcher);
 dialog_date.setondatesetlistener(new datepickerdialog.ondatesetlistener() {
  @override
  public void ondateset(datepicker datepicker, int i, int i1, int i2) {
  toast.maketext(getapplicationcontext(), i + " " + i1 + "" + i2, toast.length_short).show();
  }
 });
 dialog_date.create();
 dialog_date.show();

//时间对话框（时。分）
timepickerdialog dialog_date = new timepickerdialog(mainactivity.this, new timepickerdialog.ontimesetlistener() {
  @override
  public void ontimeset(timepicker timepicker, int i, int i1) {
  toast.maketext(getapplicationcontext(), i + " " + i1, toast.length_short).show();
  }
 }, 18, 06, true);
 dialog_date.create();
 dialog_date.show();

布局和代码中使用

1，布局中：

2，代码中：

 //设置年月日监听器
 dp.init(dp.getyear(), dp.getmonth(), dp.getdayofmonth(), new datepicker.ondatechangedlistener() {
@override
public void ondatechanged(datepicker datepicker, int i, int i1, int i2) {
tv.settext("当前时间："+ dp.getyear()+"-"+dp.getmonth()+"-"+dp.getdayofmonth()+"  "+tp.gethour()+":"+tp.getminute());
}
  });
  //设置时分监听器
  tp.setontimechangedlistener(new timepicker.ontimechangedlistener() {
@override
public void ontimechanged(timepicker timepicker, int i, int i1) {
tv.settext("当前时间："+ dp.getyear()+"-"+dp.getmonth()+"-"+dp.getdayofmonth()+"  "+tp.gethour()+":"+tp.getminute());
}
  });
