我正在尝试从我的dialogBox打印一条消息,此消息来自API,我假装在我为其设置的TextView中打印,下面是我正在尝试做的事情和错误日志:
close = new AlertDialog.Builder(LembrarSenha.this);
close.setCancelable(true);
close.setIcon(R.drawable.ic_launcher);
String msg = mNovaSenhaRest.getNovaSenha(value).getMsg();
LayoutInflater inflater = getLayoutInflater();
View view=inflater.inflate(R.layout.titlebar, null);
TextView informativo = (TextView) view.findViewById(R.id.informacao);
informativo.setText(msg); // Line 149
close.setMessage((CharSequence) informativo);
close.setView(view);
日志:
java.lang.ClassCastException: android.widget.TextView cannot be cast to java.lang.CharSequence
10-14 16:54:25.048 22956-22956/br.com. W/System.err﹕ at br.com..LembrarSenha$asyncTask$1.run(LembrarSenha.java:149)
(LembrarSenha.java:149)=“informativo.setText(msg);”
答案 0 :(得分:2)
不应该将TextView初始化为:
TextView informativo = (TextView) view.findViewById(R.id.informacao);
因为您正在尝试向对话框添加自定义视图。您的视图会膨胀,但在初始化TextView时,您不会在自定义布局中查找它。
