如何在自定义对话框中创建正面和负面按钮

更新时间:2023-02-16 19:42:32

我只是制作你自己的自定义类来模拟一个 AlertDialog,这样你就可以使用你自己的布局而不附加任何字符串.(如果您想要一个完全样式化的 AlertDialog,则存在一些无法完全摆脱框架的奇怪问题).类似这样的东西,但您可以随意扩展它:

I'd just make your own custom class to simulate an AlertDialog, this way you can use your own layout with no strings attached. (There are some weird issues where you can't fully get rid of the frame if you want a fully styled AlertDialog). Something like this, but you can expand this as fully as you want:

public class CustomDialog extends Dialog {
    private Button positive, negative;

    public CustomDialog(Context context) {
        super(context);
        initialize(context);
    }

    protected CustomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
        initialize(context);
    }

    public CustomDialog(Context context, int theme) {
        super(context, theme);
        initialize(context);
    }

    private void initialize(Context c) {
        //Inflate your layout, get a handle for the buttons

        positive = (Button)layout.findViewById(R.id.positive):
        negative = (Button)layout.findViewById(R.id.negative):

        positive.setVisibility(View.GONE);
        negative.setVisibility(View.GONE);
    }

    public void setPositiveButton(String buttonText, View.OnClickListener listener) {
        positive.setText(buttonText);
        positive.setOnClickListener(listener);
        positive.setVisibility(View.VISIBLE);
    }

    public void setNegativeButton(String buttonText, View.OnClickListener listener) {
        negative.setText(buttonText);
        negative.setOnClickListener(listener);
        negative.setVisibility(View.VISIBLE);
    }
}
