問題描述

我想創建一個自定義對話框.所以我創建了一個模板dialog_change"并打開了對話框.

I want to create a custom dialog. So i create a template 'dialog_change' and I open the dialog.

Dialog myDialog = new Dialog(Overview.this);
myDialog.setContentView(R.layout.dialog_change);
myDialog.setTitle("My Custom Dialog Title");
myDialog.show();

現在我想在底部添加兩個按鈕(一個正按鈕和一個負按鈕).我該怎么做?

Now i want to add two button (one positive and one negative button), at the bottom. How can i do that?

我只是制作你自己的自定義類來模擬一個 AlertDialog，這樣你就可以使用你自己的布局而不附加任何字符串.(如果您想要一個完全樣式化的 AlertDialog，則存在一些無法完全擺脫框架的奇怪問題).類似這樣的東西，但您可以隨意擴展它:

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);
    }
}
