Question

这是代码：

public void onClick(DialogInterface dialog, int whichButton)
    {
        Toast.makeText(getBaseContext(), "Cancel clicked", Toast.LENGTH_SHORT);

    }
}
builder.setMultiChoiceItems(items , itemsChecked,
        new DialogInterface.OnMultiChoiceClickListener()
{
    public void onClick(DialogInterface dialog, int which, boolean isChecked)
    {
        Toast.makeText(getBaseContext(), items[which]+ (isChecked ? "checked!" : "unchecked!"),
                Toast.LENGTH_SHORT).show();

    }
});

虽然代码对我来说是正确的，但我得到了许多花括号相关的错误..请帮助!!

Answer 1

public void onClick(DialogInterface dialog, int whichButton)
    {
        Toast.makeText(getBaseContext(), "Cancel clicked", Toast.LENGTH_SHORT);



builder.setMultiChoiceItems(items , itemsChecked,
        new DialogInterface.OnMultiChoiceClickListener()
{
    public void onClick(DialogInterface dialog, int which, boolean isChecked)
    {
        Toast.makeText(getBaseContext(), items[which]+ (isChecked ? "checked!" : "unchecked!"),
                Toast.LENGTH_SHORT).show();

    }
});
}

用这个替换你的代码......

builder.setMultiChoiceItems(items , itemsChecked, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
    Toast.makeText(getBaseContext(), items[which]+ (isChecked ? "checked!" : "unchecked!"), Toast.LENGTH_SHORT).show();
}
});

Answer 3

你只需要在最后一行添加一个简单的括号'）'。

});

见下文

builder.setMultiChoiceItems(items , itemsChecked,
        new DialogInterface.OnMultiChoiceClickListener()
{
    public void onClick(DialogInterface dialog, int which, boolean isChecked)
    {
        Toast.makeText(getBaseContext(), items[which]+ (isChecked ? "checked!" : "unchecked!"),
                Toast.LENGTH_SHORT).show();

    }
});

Answer 4

public void onClick(DialogInterface dialog, int whichButton)
    {
        Toast.makeText(getBaseContext(), "Cancel clicked", Toast.LENGTH_SHORT).show();<//here you missed to call show method

    }
}

builder.setMultiChoiceItems(items , itemsChecked,
        new DialogInterface.OnMultiChoiceClickListener()
{
    public void onClick(DialogInterface dialog, int which, boolean isChecked)
    {
        Toast.makeText(getBaseContext(), items[which]+ (isChecked ? "checked!" : "unchecked!"),
                Toast.LENGTH_SHORT).show();

    }
});//here to add ')' before semicolon
