Question

我正在尝试将一些文本置于默认的Alert Dialog Builder中到目前为止，这是我的代码，但默认为左侧。

            new AlertDialog.Builder(getActivity())
                    .setTitle("Well done!")
                    .setMessage("Message centered????")

                    .setPositiveButton("OK",
                            new DialogInterface.OnClickListener() {

                                @Override
                                public void onClick(DialogInterface dialog,
                                        int which) {
                                    // TODO Auto-generated method stub

                                }
                            })

                    .setIcon(R.drawable.img_ok)
                    .show();

        }

Answer 1

默认情况下，这段代码可以完成工作，而不会为AlertDialog.Builder提供自己的自定义视图。

  AlertDialog dialog = builder.show(); //builder is your just created builder
    TextView messageText = (TextView)dialog.findViewById(android.R.id.message);
    messageText.setGravity(Gravity.CENTER);
    dialog.show();

Answer 2

不要设置消息，而是使用带有居中文字的AlertDialog.Builder.setView(View)的{{1}}

Answer 3

你可以试试这段代码

public void Info(){
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Info Aplikasi");
    builder.setIcon(R.drawable.info_adp);
    builder.setMessage("Jakarta Hospital");
    builder.setCancelable(false);
    builder.setPositiveButton("Exit", null);
    AlertDialog dialog = builder.show();
    TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
    messageView.setGravity(Gravity.CENTER);
}

Answer 4

您可以尝试这种简单的方法：

textView.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
textView.setGravity(Gravity.CENTER);
alert.setView(textView);

如何在Alert Dialog Builder中居中文本？
