android - Alertdialog 显示图像和标题

Question

我正在做一个 AlertDialog，它有一个图像和一个标题:

AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle("Recuerda tirar del cable");
builder.setIcon(context.getResources().getDrawable(R.drawable.tira_cable));

builder.setPositiveButton(R.string.accept, new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int id) {
        //actions
      }
});
AlertDialog dialog = builder.create();
dialog.show();

标题未显示:

标题在哪里？我听不懂!

Answer 1

我不是 100% 确定这是否会产生影响，但我不认为额外的“噪音”，因为在 .setIcon 中缺乏更好的术语是必要的。尝试:

AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle("Recuerda tirar del cable");
builder.setIcon(R.drawable.tira_cable);

builder.setPositiveButton(R.string.accept, new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int id) {
        //actions
      }
});
AlertDialog dialog = builder.create();
dialog.show();
