Android customized button; changing text color

问题

I made a button that changes the background drawable on different states, this way:

 <selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_pressed="true" android:drawable="@drawable/btn_location_pressed" /> <!-- pressed -->
 <item android:state_focused="true" android:drawable="@drawable/btn_location_pressed"/> <!-- focused -->
 <item android:drawable="@drawable/btn_location"/> <!-- default -->

The problem here is that I'm also trying to change the textColor as I do with the drawable but I'm not being able to. I already tried android:textColor and android:color but the first doesn't work whilst the seconds changes my background.

The next code is part of my layout. Regarding to the text color it only works for the normal state text color, thus not changing it to the white one while pressed

<Button android:id="@+id/location_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingTop="5dp"
        android:background="@drawable/location"          
        android:textSize="15sp"
        android:textColor="@color/location_color"
        android:textColorHighlight="#FFFFFF"
   />

Has anybody got a clue?

Create a stateful color for your button, just like you did for background, for example:

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Focused and not pressed -->
    <item android:state_focused="true" 
          android:state_pressed="false" 
          android:color="#ffffff" />

    <!-- Focused and pressed -->
    <item android:state_focused="true" 
          android:state_pressed="true" 
          android:color="#000000" />

    <!-- Unfocused and pressed -->
    <item android:state_focused="false" 
          android:state_pressed="true" 
          android:color="#000000" />

    <!-- Default color -->
    <item android:color="#ffffff" />

</selector>

Place the xml in a file at res/drawable folder i.e. res/drawable/button_text_color.xml. Then just set the drawable as text color:

android:textColor="@drawable/button_text_color"

Another way to do it is in your class:

import android.graphics.Color; // add to top of class  

Button btn = (Button)findViewById(R.id.btn);

// set button text colour to be blue
btn.setTextColor(Color.parseColor("blue"));

// set button text colour to be red
btn.setTextColor(Color.parseColor("#FF0000"));

// set button text color to be a color from your resources (could be strings.xml)
btn.setTextColor(getResources().getColor(R.color.yourColor));

// set button background colour to be green
btn.setBackgroundColor(Color.GREEN);

ok very simple first go to 1. res-valuse and open colors.xml 2.copy 1 of the defined text their for example #FF4081 and change name for instance i changed to white and change its value for instance i changed to #FFFFFF for white value like this

<color name="White">#FFFFFF</color>

then inside your button add this line

 b3.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.White));

ok b3 is the name of my button so changed of the name of ur button all others will be same if u use white color if you change different color then change white to the name of your color but first you have define that color in colors.xml like i explained in pont 2

Changing text color of button

Because this method is now deprecated

button.setTextColor(getResources().getColor(R.color.your_color));

I use the following:

button.setTextColor(ContextCompat.getColor(mContext, R.color.your_color));

回答5:

Use getColorStateList like this

setTextColor(resources.getColorStateList(R.color.button_states_color))

instead of getColor

setTextColor(resources.getColor(R.color.button_states_color))
