How to center text in Alert Dialog Builder?
提问by Violin Nz
I'm trying to center some text in a default Alert Dialog Builder Here's my code so far, but it defaults to the left.
我正在尝试在默认警报对话框生成器中居中一些文本 这是我目前的代码,但它默认在左侧。
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();
}

Instead of setting the message, use AlertDialog.Builder.setView(View)
with a View
with centred text
相反,设置消息的,使用AlertDialog.Builder.setView(View)
了View
与居中的文本

This piece of code does the job by default, without providing your own custom view to the AlertDialog.Builder
.
这段代码默认完成这项工作,无需向AlertDialog.Builder
.
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();
