问题描述
我一直在试图使动作条标志,或向上按钮,文本,而不是图像。 actionbar.setLogo();
只接受一个绘制资源。充气带布局的的TextView
并没有这样的伎俩。
I've been trying to make the ActionBar logo, or the Up button, a text instead of an image. actionbar.setLogo();
accepts only a drawable resource. Inflating a layout with a TextView

第一个是从安卓4.2新DeskClock应用程序,第二个是从联系人应用程序。我检查了code在GitHub上,但我无法找到任何东西。

推荐答案
下面是@ CommonsWare的选项#1的实现,完美的作品。
Here is an implementation of @CommonsWare's option #1, works perfectly.
TextView upTextView = (TextView) getLayoutInflater().inflate(
R.layout.up_text, null);
upTextView.setText("CITIES");
upTextView.measure(0, 0);
upTextView.layout(0, 0, upTextView.getMeasuredWidth(),
upTextView.getMeasuredHeight());
Bitmap bitmap = Bitmap.createBitmap(upTextView.getMeasuredWidth(),
upTextView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
upTextView.draw(canvas);
BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(), bitmap);
R.layout.up_text
:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:textColor="#f00"
android:textSize="20sp"
android:textStyle="bold" />
