确认选择器

private void showDialog1() { // TODO Auto-generated method stub AlertDialog.Builder builder = new AlertDialog.Builder( MainActivity.this); builder.setTitle("确认对话框"); // 设置标题 builder.setIcon(R.drawable.ic_launcher);//设置图片 builder.setMessage("确认对话框的提示内容"); builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override &n 3ff8 bsp;public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "succeed", Toast.LENGTH_SHORT) .show(); } }); builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show(); }

单项选择器

public void onClick(View v) { AlertDialog.Builder builder = new AlertDialog.Builder( MainActivity.this); builder.setTitle("选择你的性别"); builder.setIcon(R.drawable.ic_launcher); builder.setSingleChoiceItems(single_list, 0, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub } }); // 数组 选中次数 AlertDialog dialog = builder.create(); dialog.show(); }

多项选择器（带取消按键）

private void showDialog1() { // TODO Auto-generated method stub AlertDialog.Builder builder = new AlertDialog.Builder( MainActivity.this); builder.setTitle("选择你的年纪"); // 0 builder.setIcon(R.drawable.ic_launcher); builder.setMultiChoiceItems(multi_list, null, new OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { // TODO Auto-generated method stub if (isChecked) { Toast.makeText( MainActivity.this, "你选择的是" + multi_list[which], Toast.LENGTH_SHORT).show(); } else { Toast.makeText( MainActivity.this, "你没选择的是" + multi_list[which], Toast.LENGTH_SHORT).show(); } } });// 数组 是否选中 点击事件 // 添加取消按钮 builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub dialog.dismiss();// 隐藏对话框 } }); AlertDialog dialog = builder.create();// 创建 获取dialog builder.show();// 显示对话框 }
