安卓ListView里onItemClick如何添加AlertDialog

在onItemClick方法中添加AlertDialog的步骤如下：

1. 创建AlertDialog.Builder对象

AlertDialog.Builder builder = new AlertDialog.Builder(context);

2. 设置AlertDialog的标题、消息内容和按钮

builder.setTitle("提示");
builder.setMessage("确定要删除该项吗？");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 确定按钮的点击事件
    }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 取消按钮的点击事件
    }
});

3. 创建AlertDialog对象并显示

AlertDialog dialog = builder.create();
dialog.show();

完整的示例代码如下：

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("提示");
        builder.setMessage("确定要删除该项吗？");
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 确定按钮的点击事件
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 取消按钮的点击事件
            }
        });
        AlertDialog dialog = builder.create();
        dialog.show();
    }
});
