如何设置动作条标识为文本（TextView的）？ [英] How to set ActionBar logo to Text (TextView)?

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 didn't do the trick.

基本上，我想要做到的是这样的：

Basically, what I'm trying to accomplish is this:

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" />
