Body
copied!<p>I have a button with set color code:</p> <pre><code>buttonClicked.setTextColor(Color.GRAY); </code></pre> <p>Now when I finish my timer, the text of all buttons reset to something else, so I need that text to go back to default. I tried this but I get error (i placed a comment near the end of my code for that error):</p> <pre><code>final OnClickListener clickListener = new OnClickListener() { private Button buttonClicked; private int brojacKlikova = 0; public void onClick(View v) { brojacKlikova++; if (brojacKlikova < 16) { Button button = (Button) v; button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x003333)); if (buttonClicked == null) { // first button is clicked buttonClicked = button; } else { // second button is clicked if (buttonClicked.getTag().equals(button.getTag())) { button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33)); buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33)); buttonClicked.setEnabled(false); button.setEnabled(false); counter = counter + 5; score.setText("Poeni: " + counter); } else { buttonClicked.setEnabled(false); buttonClicked.setTextColor(Color.GRAY); buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFCC99)); button.getBackground().clearColorFilter(); } buttonClicked = null; } }else{ buttonClicked = null; buttonClicked.setTextColor(Color.WHITE); //<--- here I get error brojacKlikova = 0; brojacVremena.cancel(); mHandler.postDelayed(mLaunchTask,2200); } } }; </code></pre> <p>How to reset my button's text color to default?</p> <p>Here's logcat:</p> <pre><code>03-28 23:59:29.357: W/dalvikvm(27918): threadid=1: thread exiting with uncaught exception (group=0x40018560) 03-28 23:59:29.467: E/AndroidRuntime(27918): FATAL EXCEPTION: main 03-28 23:59:29.467: E/AndroidRuntime(27918): java.lang.NullPointerException 03-28 23:59:29.467: E/AndroidRuntime(27918): at rs.androidaplikacije.spojnice.Spojnice$1.onClick(Spojnice.java:77) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.view.View.performClick(View.java:2506) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.view.View$PerformClick.run(View.java:9112) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.os.Handler.handleCallback(Handler.java:587) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.os.Handler.dispatchMessage(Handler.java:92) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.os.Looper.loop(Looper.java:130) 03-28 23:59:29.467: E/AndroidRuntime(27918): at android.app.ActivityThread.main(ActivityThread.java:3835) 03-28 23:59:29.467: E/AndroidRuntime(27918): at java.lang.reflect.Method.invokeNative(Native Method) 03-28 23:59:29.467: E/AndroidRuntime(27918): at java.lang.reflect.Method.invoke(Method.java:507) 03-28 23:59:29.467: E/AndroidRuntime(27918): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:864) 03-28 23:59:29.467: E/AndroidRuntime(27918): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:622) 03-28 23:59:29.467: E/AndroidRuntime(27918): at dalvik.system.NativeStart.main(Native Method) 03-28 23:59:31.167: I/Process(27918): Sending signal.
