对话框整理

普通对话框

/*** 普通对话框* * 对话框中的一些属性不一定是必须的，比如可以不设置标题、图标之类的，* * 也可以只设置一个按钮或者两个按钮，如常见的确认退出对话框*/private void commonDialog() {AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("普通对话框");// 设置标题// builder.setIcon(R.drawable.ic_launcher);//设置图标builder.setMessage("我是内容");// 为对话框设置内容// 为对话框设置取消按钮builder.setNegativeButton("取消", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubmyToast("您点击了取消按钮");}});// 为对话框设置中立按钮// builder.setNeutralButton("中立", new OnClickListener() {//// @Override// public void onClick(DialogInterface arg0, int arg1) {// // TODO Auto-generated method stub// myToast("您点击了中立按钮");// }// });// 为对话框设置确定按钮builder.setPositiveButton("确定", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubmyToast("您点击了确定按钮");}});builder.create().show();// 使用show()方法显示对话框}

单选对话框

/*** 单选对话框*/private void singleDialog() {AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("单选对话框");final String[] items = { "男", "女" };// 创建一个存放选项的数组final boolean[] checkedItems = { true, false };// 存放选中状态，true为选中// ，false为未选中，和setSingleChoiceItems中第二个参数对应// 为对话框添加单选列表项// 第一个参数存放选项的数组，第二个参数存放默认被选中的项，第三个参数点击事件builder.setSingleChoiceItems(items, 0, new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubfor (int i = 0; i < checkedItems.length; i++) {checkedItems[i] = false;}checkedItems[arg1] = true;}});builder.setNegativeButton("取消", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubarg0.dismiss();}});builder.setPositiveButton("确定", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubString str = "";for (int i = 0; i < checkedItems.length; i++) {if (checkedItems[i]) {str = items[i];}}myToast("您选择了" + str);}});builder.create().show();}

多选对话框

/*** 多选对话框*/private void multipleDialog() {AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("多选对话框");final String[] items = { "数学", "语文", "英语", "政治" };// 存放选项的数组final boolean[] checkedItems = { false, true, false, false };// 第一个参数选项，第二个参数选项的状态，第三个点击事件builder.setMultiChoiceItems(items, checkedItems,new OnMultiChoiceClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1,boolean arg2) {// TODO Auto-generated method stubif (arg2) {checkedItems[arg1] = true;} else {checkedItems[arg1] = false;myToast("您取消了" + items[arg1]);}}});builder.setNegativeButton("取消", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubarg0.dismiss();}});builder.setPositiveButton("确定", new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubString str = "";for (int i = 0; i < checkedItems.length; i++) {if (checkedItems[i]) {str = str + items[i];}}myToast("您选择了" + str);}});builder.create().show();}

列表对话框

/*** 列表对话框*/private void listDialog() {final String[] items = { "苹果", "草莓", "橘子", "冬瓜" };AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("我是列表对话框");builder.setItems(items, new OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stubmyToast(items[arg1]);}});builder.create().show();}

不带进度条的对话框，常用于等待加载数据时使用

/*** 不带进度条的对话框，常用于等待加载数据时使用*/private void proDialog1() {ProgressDialog dialog = new ProgressDialog(MainActivity.this);dialog.setTitle("不带进度条的对话框");dialog.setMessage("正在加载中~");dialog.show();}

带进度的对话框

/*** 带进度的对话框*/private void proDialog2() {final ProgressDialog dialog = new ProgressDialog(MainActivity.this);dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 设置水平样式dialog.setTitle("带进度条的对话框");dialog.setMessage("加载中~");dialog.setMax(200);dialog.show();new Thread(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubfor (int j = 0; j <= 200; j++) {try {Thread.sleep(100);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}dialog.setProgress(j);}}}).start();}

自定义布局的对话框

/*** 自定义布局的对话框*/private void layDialog() {AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);// 创建一个view，并且将布局加入view中View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog_edt, null, false);// 将view添加到builder中builder.setView(view);// 创建dialogfinal Dialog dialog = builder.create();// 初始化控件，注意这里是通过view.findViewByIdfinal EditText edt = (EditText) view.findViewById(R.id.edt);Button confirm = (Button) view.findViewById(R.id.confirm);Button cancel = (Button) view.findViewById(R.id.cancel);// 设置button的点击事件及获取editview中的文本内容confirm.setOnClickListener(new android.view.View.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubString str = edt.getText() == null ? "" : edt.getText().toString();myToast(str);}});// 取消按钮cancel.setOnClickListener(new android.view.View.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubdialog.dismiss();}});dialog.show();}
