How to use colorstatelist in android

Question

I want to change the color of the button text in different states such as btn_presses, btn_focus, etc.

For this, I use colorstatelist.xml and I redefined it in the button text in titlebarlayout.xml. But still I can’t change the color of the button text.

Does anyone know how to do this. I am mistaken in the code.

MainActivity.java

public class MainActivity extends Activity implements OnClickListener { EditText emailEdit, passwordEdit; Button loginButton; String email, password; TitleBarLayout titlebarLayout; String r; String rr; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.login_activity); emailEdit = (EditText) findViewById(R.id.etEmail); passwordEdit = (EditText) findViewById(R.id.etPassword); loginButton = (Button) findViewById(R.id.loginButton); loginButton.setOnClickListener(this); // titlebarLayout=(TitleBarLayout) findViewById(R.id.titlebar); titlebarLayout = new TitleBarLayout(MainActivity.this); titlebarLayout.setLeftButtonText(""); titlebarLayout.setRightButtonText("Logout"); titlebarLayout.setTitle("iProtect"); //titlebarLayout.setLeftButtonSize(50,50); //titlebarLayout.setRightButtonSize(100,50); titlebarLayout.setLeftButtonBackgroundColor(Color.rgb(34,49,64)); titlebarLayout.setRightButtonBackgroundColor(Color.rgb(34,49,64)); titlebarLayout.setLeftButtonTextColor(Color.rgb(255,255,255)); titlebarLayout.setRightButtonTextColor(Color.rgb(255,255,255)); XmlResourceParser parser =getResources().getXml(R.color.colorstatelist); ColorStateList colorStateList; try { colorStateList = ColorStateList.createFromXml(getResources(), parser); titlebarLayout.setLeftButtonTextColor(colorStateList); } catch (XmlPullParserException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } // ColorStateList colorlist=new ColorStateList( new int[][] { new int[] { android.R.attr.state_focused }, new int[0], }, new int[] { Color.rgb(0, 0, 255), Color.BLACK, } ); // titlebarLayout.setLeftButtonTextColor(colorlist); OnClickListener listener = new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if (v.getId() == R.id.left_button) { } else if (v.getId() == R.id.right_button) { } } }; titlebarLayout.setLeftButtonOnClickListener(listener); titlebarLayout.setRightButtonOnClickListener(listener); } 

TitleBarLayout.java

 public class TitleBarLayout { private Activity activityRef; private View contentView; private Button leftButton, rightButton; TextView titletext; public TitleBarLayout(Activity a) { Log.i("TitleBar Layout", "Inside constructor"); activityRef = a; inflateViewsFromXml(); setListenersOnViews(); setValuesOnViews(); } private void setValuesOnViews() { leftButton.setText(""); rightButton.setText(""); } private void setListenersOnViews() { leftButton.setOnClickListener(listener); rightButton.setOnClickListener(listener); } private final OnClickListener listener = (new OnClickListener() { @Override public void onClick(View v) { activityRef.finish(); } }); private void inflateViewsFromXml() { contentView = activityRef.findViewById(R.id.titlebar); rightButton = (Button) contentView.findViewById(R.id.right_button); leftButton = (Button) contentView.findViewById(R.id.left_button); titletext = (TextView) contentView.findViewById(R.id.title_textview); } public void setLeftButtonText(int resID) { leftButton.setText(resID); } public void setLeftButtonText(String text) { leftButton.setText(text); } public void setLeftButtonOnClickListener(View.OnClickListener listener) { leftButton.setOnClickListener(listener); } public void setRightButtonText(int resID) { rightButton.setText(resID); } public void setRightButtonText(String text) { rightButton.setText(text); } public void setRightButtonOnClickListener(View.OnClickListener listener) { rightButton.setOnClickListener(listener); } public void setTitle(int resID) { titletext.setText("" + resID); } public void setTitle(String text) { titletext.setText(text); } public void setLeftButtonSize(int width, int height) { Log.i("Button" ,"Width"+width); leftButton.setWidth(width); leftButton.setHeight(height); } public void setRightButtonSize(int width, int height) { Log.i("Button" ,"Width"+width); rightButton.setWidth(width); rightButton.setHeight(height); } public void setLeftButtonBackgroundResource(int backgroundResource) { } public void setRightButtonBackgroundResource(int backgroundResource) { } public void setLeftButtonBackgroundColor(int backgroundColor) { Log.i("Button" ,"COLOR"+backgroundColor); leftButton.setBackgroundColor(backgroundColor); } public void setRightButtonBackgroundColor(int backgroundColor) { Log.i("Button" ,"COLOR"+backgroundColor); rightButton.setBackgroundColor(backgroundColor); } public void setLeftButtonTextColor(int textcolor) { Log.i("Button" ,"COLOR"+textcolor); leftButton.setTextColor(textcolor); } public void setRightButtonTextColor(int textcolor) { Log.i("Button" ,"COLOR"+textcolor); rightButton.setTextColor(textcolor); } public void setLeftButtonTextColor(ColorStateList colorStateList) { leftButton.setTextColor(colorStateList); } public void setRightButtonTextColor(ColorStateList colorStateList) { } } 

color.xml

 <?xml version="1.0" encoding="utf-8"?> <resources> <color name="title_bg_color">#2e4256</color> <color name="layout_bg_color">#dcdcdc</color> <color name="state_pressed">#ffffff</color> <color name="state_selected">#00ff00</color> <color name="state_focused">#0000ff</color> </resources> 

titlebarlayout.xml

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="@dimen/titlebar_height" android:background="@color/title_bg_color" android:gravity="center_vertical" android:orientation="horizontal" > <Button android:id="@+id/left_button" android:layout_width="@dimen/titlebar_button_width" android:layout_height="@dimen/titlebar_button_height" android:text="" android:clickable="true" android:textColor="@color/colorstatelist" android:background="@drawable/button_shape_drawable" android:layout_marginLeft="10dp"/> <TextView android:id="@+id/title_textview" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" android:gravity="center" android:text="" android:textColor="@android:color/white" android:textStyle="bold" /> <Button android:id="@+id/right_button" android:layout_width="@dimen/titlebar_button_width" android:layout_height="@dimen/titlebar_button_height" android:text="" android:clickable="true" android:layout_marginRight="10dp" android:background="@drawable/button_shape_drawable" android:textColor="@color/colorstatelist" /> </LinearLayout> 

colorstatelist.xml

 <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:color="@color/state_pressed"/> <item android:state_selected="true" android:color="@color/state_selected"/> <item android:state_focused="true" android:color="@color/state_focused"/> <item android:color="#808080"/> </selector>

First, get rid of all the XML parsing from your code. All this adds some errors. There are two approaches that you could use, and you should use one or the other , not both.

Your XML format already sets android:textColor to the list of states you want. That is all you have to do. The button text will automatically change color according to its state. Just remove all calls to setTextColor from your Java code: these calls currently replace the list of states with static color. I suggest you completely remove the setLeft/RightButtonTextColor from your TitleBarLayout.java , and then let your IDE find all the calls and delete them.

Alternatively, if you want to set the color from Java code instead of XML, you just need to call it like this: -

 button.setTextColor(getResources().getColorStateList(R.color.colorstatelist)); 

No XML parsing needed.
