android:capitalize not working

问题:

I have a TextView. I'm trying to capitalize the first letter in every word.

Here's the TextView:

 <TextView 
            android:text="TextView" 
            android:id="@+id/textView1" 
            android:layout_height="wrap_content" 
            android:layout_width="wrap_content" 
            android:layout_alignParentRight="true" 
            android:textSize="30dip" 
            android:textStyle="bold" 
            android:layout_marginRight="5dip" 
            android:ellipsize="end"
            android:capitalize="words">
        </TextView>

Here's how I'm adding the text:

TextView titleView = (TextView) findViewById(R.id.textView1);
    titleView.setText( section.replace("_", " ") );

Can I not add text dynamically and expect it to capitalize the words? Is another trait interfering with android:capitalize? Is android:capitalize broken?

Thanks for your replies.

回答1:

capitalize is basically just a KeyListener that you can set in XML, so it only applies to text input by the user. As the documentation states (emphasis mine):

If set, specifies that this TextView has a textual input method and should automatically capitalize what the user types.

There is a related question on how to capitalize the first letter of every word in Java which has some helpful answers.

回答2:

If you're targeting API Level 14 and above, you should use

android:textAllCaps="true"

Otherwise, you'll have to implement this behavior yourself.

回答3:

android:capitalize is now deprecated.

Instead of using android:capitalize="words", you should consider using android:inputType="textCapWords".

Depending on your needs, you can also use multiple values, such as android:inputType="textCapWords|textPersonName".

This is a late answer but I think might help someone...

If you are comfortable with capitilizing the dynamic text in the java code then you can use:

textView.setText(text.toUpperCase()); 

回答5:

@Shine's answer is correct I don't know why it was down voted. android:capitalize was deprecated in API 3. Unfortunately the TextView docs fail to indicate this, the proof is burried in R.attr:

R.attr

Android studio also fails to inform you that this attribute is deprecated. Another 30 mins I'll never get back, thanks google!

回答6:

android:capitalize is deprecated on ICS, so I guess it should be better to do it in code (i.e. with String.toUpperCase())

Another try could be

 android:inputType="textCapWords"

but I guess it would require an EditText to work.

I don't know if this is the reason for your code, what version are you targeting?
