普通的dialog:
private void plaindialogdemo() { button plainbtn = (button) findviewbyid(r.id.plaindialog); plainbtn.setonclicklistener(new onclicklistener() { public void onclick(view v) { new alertdialog.builder(dialogactivity.this) .settitle("删除") .setmessage("确定删除指定数据") .setpositivebutton("确定", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { toast.maketext(getapplicationcontext(), "确定了", toast.length_short) .show(); } }) .setnegativebutton("取消", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { } }).setcancelable(false).show(); } }); }
效果如下:
输入文本框的dialog:
private void inputdialog() { button inputbtn = (button) findviewbyid(r.id.inputdialog); inputbtn.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { // todo auto-generated method stub final edittext et = new edittext(dialogactivity.this); new alertdialog.builder(dialogactivity.this) .settitle("请输入数字") .setview(et) .setpositivebutton("确定", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { // todo auto-generated method stub toast.maketext(getapplicationcontext(), et.gettext(), toast.length_short).show(); } }).setnegativebutton("取消", null) .setcancelable(false).show(); } }); }
效果如下:
列表dialog:
private void listdialogdemo() { button listbtn = (button) findviewbyid(r.id.listdialog); listbtn.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { final string[] names = { "c罗", "j罗", "h罗" }; new alertdialog.builder(dialogactivity.this).settitle("列表对话框") .setitems(names, new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { toast.maketext(dialogactivity.this, names[which], toast.length_short) .show(); } }).setnegativebutton("取消", null).show(); } }); }
效果如下:
单选dialog:
private void radiodialogdemo() { button radiobutton = (button) findviewbyid(r.id.radiodialog); radiobutton.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { final string[] names = { "c罗", "j罗", "h罗" }; new alertdialog.builder(dialogactivity.this) .settitle("列表对话框") .setsinglechoiceitems(names, , new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { selectename = names[which]; } }) .setpositivebutton("确定", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { toast.maketext(dialogactivity.this, selectename, toast.length_short) .show(); } }).setnegativebutton("取消", null).show(); } }); }
效果如下:
多选dialog:
private void checkdialogdemo() { button checkbtn = (button) findviewbyid(r.id.checkboxdialog); checkbtn.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { final string[] names = { "c罗", "j罗", "h罗" }; final boolean[] selected = new boolean[] { true, false, true }; new alertdialog.builder(dialogactivity.this) .setmultichoiceitems( names, selected, new dialoginterface.onmultichoiceclicklistener() { @override public void onclick(dialoginterface dialog, int which, boolean ischecked) { } }) .setpositivebutton("确定", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { stringbuilder sb = new stringbuilder( "你选择了:"); for (int i = ; i < names.length; i++) { if (selected[i]) { sb.append(names[i]); } } toast.maketext(dialogactivity.this, sb.tostring(), ).show(); } }).setnegativebutton("取消", null).show(); } }); }
效果如下:
自定义dialog:
private void customdialogdemo() { final alertdialog dlg = new alertdialog.builder(this).create(); dlg.show(); window window = dlg.getwindow(); window.setcontentview(r.layout.diylayout); imagebutton ok = (imagebutton) window.findviewbyid(r.id.btnok); ok.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { toast.maketext(getapplicationcontext(), "关闭了", toast.length_short).show(); dlg.dismiss(); } }); }
自定义布局:
<?xml version="." encoding="utf-"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <imageview android:id="@+id/dialogimg" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerinparent="true" android:src="@drawable/dialog_bg" /> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignleft="@id/dialogimg" android:layout_aligntop="@id/dialogimg" android:layout_marginleft="dp" android:layout_margintop="dp" android:text="自定义的dialog" /> <imagebutton android:id="@+id/btnok" android:layout_width="dp" android:layout_height="dp" android:layout_alignright="@id/dialogimg" android:layout_aligntop="@id/dialogimg" android:layout_marginright="dp" android:layout_margintop="dp" android:background="@drawable/close_dialog" /> </relativelayout>
效果如:
