具有自定义字体的 AlertDialogPro
AlertDialogPro with custom Typeface
我正在尝试为使用 AlertDialogPro 构建的对话框设置自定义字体,但在尝试使用 dialog.getButton(int)
检索对话框按钮时出现 NPE。以及如何设置消息的字体和对话框的标题?
AlertDialogPro.Builder builder = new AlertDialogPro.Builder(this);
builder.setMessage(getResources().getString(R.string.dialog_body))
.setPositiveButton(getResources().getString(R.string.ok), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Do stuff
}
});
AlertDialogPro dialog = builder.create();
dialog.getButton(DialogInterface.BUTTON_POSITIVE).setTypeface(customTf));
dialog.show();
日志:
03-02 16:30:22.982: E/AndroidRuntime(15596):
java.lang.NullPointerException: Attempt to invoke virtual method 'void android
.widget.Button.setTypeface(android.graphics.Typeface)' on a null
object reference
调用此方法:
builder.setPositiveButton(int textId,final OnClickListener listener)
创建对话框之前
您只能在调用 dialog.show()
后访问对话框按钮(通过 dialog.getButton(DialogInterface.BUTTON_POSITIVE)
)。
通过做两件事修复了它:
- 将 getButton() 移到 dialog.show()
之后
- 使用 findViewById() 检索消息文本视图
代码:
AlertDialogPro.Builder builder = new AlertDialogPro.Builder(this);
builder.setMessage(getResources().getString(R.string.dialog_body))
.setPositiveButton(getResources().getString(R.string.ok), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Do stuff
}
});
AlertDialogPro dialog = builder.create();
dialog.show();
dialog.getButton(DialogInterface.BUTTON_POSITIVE).setTypeface(customTf));
((TextView) dialog.findViewById(R.id.adp_message)).setTypeface(customTf);
