【Android】对话框

1.警告对话框

button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("提示");builder.setMessage("你确定要删除吗？");builder.setIcon(R.drawable.ic_launcher);builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub//完成用户的操作，提交请求dialog.dismiss();}});builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub//取消用户操作dialog.dismiss();}});builder.setNeutralButton("忽略", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub//忽略用户操作}});AlertDialog alertDialog = builder.create();alertDialog.show();}});

2.列表对话框

button2.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("请选择以下城市");//builder.setMessage("请选择以下城市");//不能设置msg的内容builder.setItems(items, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubString select_item = items[which].toString();Toast.makeText(MainActivity.this, "-->>"+ select_item, Toast.LENGTH_LONG).show();}});AlertDialog alertDialog = builder.create();alertDialog.show();}});

注意不要设置Message

3.单选列表对话框

button3.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("请选择以下城市：");builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubCharSequence select_items = items[which];Toast.makeText(MainActivity.this, select_items, 1).show();dialog.dismiss();}});AlertDialog dialog  = builder.create();dialog.show();}});

4.多选列表对话框

button4.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("请选择以下城市：");//第二个参数可以设置为空//使用Stringuffer追加，中间用逗号分割开builder.setMultiChoiceItems(R.array.city, new boolean[] {false,false,false}, new DialogInterface.OnMultiChoiceClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which, boolean isChecked) {// TODO Auto-generated method stub}});builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub//直接获取dialog的选中情况}});AlertDialog dialog = builder.create();dialog.show();}});

注意这里添加选项列表的方式，采用了资源ID

在String.xml中加入了：

<string-array name="city">        <item >北京</item>        <item >上海</item>        <item >广州</item></string-array>
