我一直在尝试用圆角制作我的警报对话框，但不知何故我做不到。我试过了，但我失败了。我试着关注这个博客http://blog.stylingandroid.com/archives/271并以此为基础制作了我的风格。
顺便说一句，现在补充我的问题。我的一些新发现。上面链接中的代码在 2.3.3 (GB) 上运行良好，但在 ICS 中根本不起作用。一些更改使代码中断。
我想避免创建 9 个补丁图像，因此我使用的是形状。9 补丁图像是我将尝试的最后一件事。我知道 android 警报对话框样式正在使用 9 补丁图像。在提出这个问题之前，我已经查过了。

我的警报对话框代码：
public static void createYesNoDialog(final Context context, String positivebuttonname,
String negativebuttonname, String message, int messagedrawable, String headermessage,
final DialogResponse dr) {
final DialogResponse dialogResponse = dr;
ContextThemeWrapper ctw = new ContextThemeWrapper(context,
com.gp4ever.worldlogo.quiz.R.style.MyTheme);
AlertDialog.Builder builder = new AlertDialog.Builder(ctw);
LayoutInflater inflater = (LayoutInflater)context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(com.gp4ever.worldlogo.quiz.R.layout.dialog_layout, null);
TextView text = (TextView)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.textView1);
Button buttonOk = (Button)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.button1);
Button buttonMore = (Button)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.button2);
text.setText(message);
if (messagedrawable > 0) {
text.setCompoundDrawablesWithIntrinsicBounds(messagedrawable, 0, 0, 0);
} else if (messagedrawable == 0)
text.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0, 0);
builder.setView(layout);
builder.setCancelable(false);
builder.setTitle(headermessage);
builder.setIcon(android.R.drawable.ic_dialog_alert);
final AlertDialog dialog = builder.create();
buttonOk.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
buttonMore.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
}
我当前的输出：
我没有得到任何圆角。我可以看到它与通常的风格不同。即使我更改了可绘制对象的半径，角也不会反映这些更改。
