TextView Font Setting Method:

1, directly through the configuration file settings
2, in the activity class to set up

The first method is simple, for setting the static or initial text color, as follows:

Main.xml

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
  android:orientation=" vertical "
  android:layout_width=" fill_parent "
  android:layout_" height= "Fill_parent"
  android:background= "@drawable/white"
  >
<textview android:id=
  "@+id/ Tv01 "
  android:layout_width=" fill_parent "
  android:layout_height=" wrap_content "
  android:text=" @ String/hello "
  android:autolink=" all "
  android:textcolor=" @color/red "
  />
</ Linearlayout>

Color.xml

<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
  <drawable name= "White" > #FFFFFF </ drawable>
  <drawable name= "Dark" > #000000 </drawable>
  <drawable name= "Red" > #FF0000 < /drawable>
</resources>
strings.xml
<?xml version= "1.0" encoding= "Utf-8"?>
< resources>
 <string name= "Hello" > Address:http://yahaitt.javaeye.com</string>
  <string name= " App_name "> Ya-Pear notebook </string>
</resources>

The Resources section is divided into 3 parts to make it clear, but you can also just build an XML file in the Res directory, and the file name can be arbitrarily named.

Note two places:

1, main.xml TextView label: android:textcolor= "@color/red"

2, Color.xml: <color name= "Red" > #FF0000 </color>

@color refers to the <color> tag that gets the resource file (the XML file in all res directories)

/red refers to the content under the label whose name value is red, whose value is #ff0000

So here's what we can do: android:textcolor= "@drawable/red"

@drawable refers to obtaining <drawable> tags in resource files

/red refers to the content under the label to find its name value red

And so on, I believe you will know what to do if it is in the strings.xml.

Let's look at the second way: set in the Activity class

1, the first main.xml into the following, that is, remove android:textcolor= "@color/red":

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
  android:orientation=" vertical "
  android:layout_width=" fill_parent "
  android:layout_" height= "Fill_parent"
  android:background= "@drawable/white"
  >
<textview android:id=
  "@+id/ Tv01 "
  android:layout_width=" fill_parent "
  android:layout_height=" wrap_content "
  android:text=" @ String/hello "
  android:autolink=" all "
  />
</LinearLayout>

2, modify the activity of the OnCreate method, where my activity is study03_01, the original code is as follows:

Package yahaitt.study03_01;
Import android.app.Activity;
Import Android.os.Bundle;
public class Study03_01 extends activity {    @Override public
  void OnCreate (Bundle savedinstancestate) {
    Super.oncreate (savedinstancestate);
    Setcontentview (R.layout.main);
  }

The first step: Get the Text control TextView, named TV

Step two: Use the TextView SetTextColor method for text color settings, there are 3 ways to set:

The 1th kind: Tv.settextcolor (Android.graphics.Color.RED);//system with color class

2nd: Tv.settextcolor (0XFFFF00FF);//0xffff00ff is an int type of data, grouped 0x|ff|ff00ff,0x is the mark representing the color integer, FF is the transparency, the FF00FF represents the color, Note: Here the FFFF00FF must be 8 colors to indicate that FF00FF is not accepted as the color representation of the 6.

3rd: Tv.settextcolor (This.getresources (). GetColor (r.color.red))//set by obtaining a resource file. Depending on the situation r.color.red can also be r.string.red or r.drawable.red, of course, if necessary in the corresponding configuration file to do the appropriate configuration, such as:

<color name= "Red" > #FF0000 </color>
<drawable name= "Red" > #FF0000 </drawable>
< String name= "Red" > #FF0000 </string>

The detailed code is as follows:

Package yahaitt.study03_01;
Import android.app.Activity;
Import android.content.res.Resources;
Import Android.graphics.Color;
Import Android.os.Bundle;
Import Android.widget.TextView;
public class Study03_01 extends activity {
  private TextView TV;
  @Override public
  void OnCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (r.layout.main);
    TV = (TextView) This.findviewbyid (R.ID.TV01);
    Tv.settextcolor (color.red);
    Tv.settextcolor (0xff000000);
  }
