如何在不使用xml的情况下更改代码中alertdialog中的按钮大小？我没有使用视图..

谢谢代码：alertbox3.setNeutralButton("Cancel",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } });

Answer 1

您可以尝试以下代码：

 AlertDialog.Builder adb = new AlertDialog.Builder(this);
 Dialog d = adb.setView(new View(this)).create();
// (That new View is just there to have something inside the dialog that can grow big enough to cover the whole screen.)

WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(d.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.FILL_PARENT;
lp.height = WindowManager.LayoutParams.FILL_PARENT;
d.show();
d.getWindow().setAttributes(lp);

您应该使用自定义视图来更改按钮布局。请参阅以下链接，了解如何为alertDialog创建自己的视图。

Answer 3

试试这个： https://stackoverflow.com/a/15910202/305135

final AlertDialog alert = builder.create();
alert.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        Button btnPositive = alert.getButton(Dialog.BUTTON_POSITIVE);
        btnPositive.setTextSize(TEXT_SIZE);

        Button btnNegative = alert.getButton(Dialog.BUTTON_NEGATIVE);
        btnNegative.setTextSize(TEXT_SIZE);
    }
});

return alert;

你为什么这么想？系统将代表您构建标准对话框布局，遵循用户期望和熟悉的约定。一般来说，你不应该试图绕过这个。
