Android开发中的普通dialog实例解析

1.取消，确认

 dialoginterface.onclicklistener dialogoncliclistener = new dialoginterface.onclicklistener() {

@override
public void onclick(dialoginterface dialog, int which) {
 switch (which) {
  case dialog.button_positive:
toast.maketext(getcontext(), "确认",
  toast.length_short).show();
break;
  case dialog.button_negative:
toast.maketext(getcontext(), "取消",
  toast.length_short).show();
break;
  case dialog.button_neutral:
toast.maketext(getcontext(), "忽略",
  toast.length_short).show();
break;
 }
}
  };

  alertdialog.builder builder = new alertdialog.builder(getcontext(),3);
  //builder.seticon(r.mipmap.ic_launcher);
  //builder.settitle("普通对话框");
  builder.setmessage("是否清除缓存?");
  builder.setpositivebutton("确认", dialogoncliclistener);
  builder.setnegativebutton("取消", dialogoncliclistener);
//  builder.setneutralbutton("忽略", dialogoncliclistener);
  builder.create().show();

2.列表

final string items[] = {"刘德华", "张柏芝", "蔡依林", "张学友"};

alertdialog.builder builder = new alertdialog.builder(this, 3);
builder.settitle("列表");
// builder.setmessage("是否确认退出?"); //设置内容
builder.seticon(r.mipmap.ic_launcher);
// 设置列表显示，注意设置了列表显示就不要设置builder.setmessage()了，否则列表不起作用。
builder.setitems(items, new dialoginterface.onclicklistener() {
 @override
 public void onclick(dialoginterface dialog, int which) {
  dialog.dismiss();
  toast.maketext(mainactivity.this, items[which],
 toast.length_short).show();

 }
});
builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {
 @override
 public void onclick(dialoginterface dialog, int which) {
  dialog.dismiss();
  toast.maketext(mainactivity.this, "确定", toast.length_short)
 .show();
 }
});
builder.create().show();

3.单选

final string items[] = {"男", "女", "其他"};
alertdialog.builder builder = new alertdialog.builder(this,3);
builder.settitle("单选");
builder.seticon(r.mipmap.ic_launcher);
builder.setsinglechoiceitems(items, 0,
  new dialoginterface.onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {

 toast.maketext(mainactivity.this, items[which],
toast.length_short).show();
}
  });
builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {
 @override
 public void onclick(dialoginterface dialog, int which) {
  dialog.dismiss();
  toast.maketext(mainactivity.this, "确定", toast.length_short)
 .show();
 }
});
builder.create().show();

4.多选

final string items[] = {"java", "c++", "javascript", "mysql"};
  final boolean selected[] = {true, false, true, false};
  alertdialog.builder builder = new alertdialog.builder(this,3);
  builder.settitle("多选");
  builder.seticon(r.mipmap.ic_launcher);
  builder.setmultichoiceitems(items, selected,
 new dialoginterface.onmultichoiceclicklistener() {
  @override
  public void onclick(dialoginterface dialog, int which,
 boolean ischecked) {

toast.maketext(mainactivity.this,
  items[which] + ischecked, toast.length_short)
  .show();
  }
 });
  builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {
@override
public void onclick(dialoginterface dialog, int which) {
 dialog.dismiss();
 toast.maketext(mainactivity.this, "确定", toast.length_short)
.show();
 // android会自动根据你选择的改变selected数组的值。
// for (int i = 0; i < selected.length; i++) {
//  log.e("hongliang", "" + selected[i]);
// }
}
  });
  builder.create().show();

5.可输入

final edittext edittext = new edittext(this);
final alertdialog.builder builder = new alertdialog.builder(this,3);
builder.settitle("可编辑");
builder.seticon(r.mipmap.ic_launcher);
builder.setview(edittext);
builder.setpositivebutton("确定", new dialoginterface.onclicklistener() {
 @override
 public void onclick(dialoginterface dialog, int which) {
  toast.maketext(mainactivity.this, edittext.gettext().tostring() + "", toast.length_long).show();
 }
});
builder.setnegativebutton("取消", new dialoginterface.onclicklistener() {
 @override
 public void onclick(dialoginterface dialog, int which) {
  dialog.cancel();
 }
});
builder.create().show();
