I was updating an existing code by introducing dismiss button, and the onClick Butterknife method is not working for dismiss button, whereas its working for close button. In the below code, I am enabling the close button for some devices and for other devices I am enabling the dismiss button. I am quite unsure why this "dismiss" button is not working, whereas the close button is working fine. And both of them use the ButterKnife, onClick method - onSkip()
InfoActivity.java :
public class InfoActivity extends BccActiviy {
#BindView(R.id.ImageView_CloseView)
ImageView tCloseView;
#BindView(R.id.Dismiss)
Button tDismiss;
.....
#OnClick({R.id.Dismiss, R.id.ImageView_CloseView})
public void onSkip(View v) {
onDissmissPressed();
}
public void initialize(Bundle savedInstanceState) {
if (tConfig.isDismiss()) {
tCloseView.setVisibility(View.GONE);
tDismiss.setVisibility(View.VISIBLE);
} else {
tDismiss.setVisibility(View.GONE);
}
}
}

Try removing the onClick from xml.
When I try to open this new activity through a button on a previous layout the app crashes with no apparent reason.
My code is this :
public class Main3Activity extends AppCompatActivity {
private int limitsImages[] = {R.drawable.onelimits, R.drawable.twolimits, R.drawable.threelimits, R.drawable.fourlimits, R.drawable.fivelimits, R.drawable.sixlimits,
R.drawable.sevenlimits, R.drawable.eightlimits, R.drawable.ninelimits, R.drawable.tenlimits};
private String answersLimits[] = {"-9", "2", "1/10", "1/6", "1/2", "12", "1", "2/3", "5/6", "1/4"};
private String choicesLimits[][] = {{"-19", "19", "-9", "2"},{"0", "-2", "Does not exist", "2"}, {"Does not exist","1/5","0","1/10"},{"1/6","1/5","1/4","1"}

,"Does not exist","4"}};
private TextView questionNum;
private TextView questionTxt;
private ImageView questionImage;
private CheckBox choiceOne;
private CheckBox choiceTwo;
private CheckBox choiceThree;
private CheckBox choiceFour;
private static int testIdentifier=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
questionNum = (TextView) findViewById(R.id.questionNumber);
questionTxt = (TextView) findViewById(R.id.questionText);
questionImage = (ImageView) findViewById(R.id.questionImage);
choiceOne = (CheckBox) findViewById(R.id.choice1);
choiceTwo = (CheckBox) findViewById(R.id.choice2);
choiceThree = (CheckBox) findViewById(R.id.choice3);
choiceFour = (CheckBox) findViewById(R.id.choice4);
//choicesLimits[4][3]=getString(R.string.doesntexist);
//choicesLimits[9][2]=getString(R.string.doesntexist);
startLimitsQuestion(testIdentifier);
}
public void startLimitsQuestion( int questionNum) {
this.questionNum.setText(questionNum+1+"/10");
questionTxt.setText(getString(R.string.limitsQ));
questionImage.setImageResource(limitsImages[questionNum]);
choiceOne.setText(choicesLimits[questionNum][1]);
choiceTwo.setText(choicesLimits[questionNum][2]);
choiceThree.setText(choicesLimits[questionNum][3]);
choiceFour.setText(choicesLimits[questionNum][4]);
}
Sub Question:I have been troubled a bit if my initialization and declaration before the onCreate() method is correct.

You said that you clicked and then it crashed. So some problem will be there in the onclick. We need to follow your code from onclick. The above snippet is just showing the first question display and these are correct except the test identifier is not incremented.
Please do post full class code of that snippet. Also do give logcat error
What i could guess is some where the error should be in registering activity to manifest or error durimg onclick where your accessing arrays. May be arrayoutofbounds too.
I have resolved your problem. The app theme you declared in your AndroidManifest.xml is not appropriate. As you are extending the AppCompatActivity in your activity, you need to use the Appcompat theme for your particular activity or application.
Change your current app theme to android:theme="#style/Theme.AppCompat.Light" in AndroidManifest.xml file will resolve your problem.
Note:: Your initialisation and declaration is perfect and your onClick method is not the issue. This AppTheme is the only issue. Tell me if you didn't get me.
Use Firebase crash library to report Crash to detect crash if you are not able to crash in logcate

Hy.... I'm making a simple project on eclipse. I'm using relative layout as shown below :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

<Button
android:id="#+id/Prof_edit_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Edit"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
/>
<LinearLayout
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerHorizontal="true"
>
<Button
android:id="#+id/Prof_save_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
android:visibility="invisible"
android:clickable="false"
/>
<Button
android:id="#+id/Prof_batal_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Batal"
android:layout_marginTop="17dp"
android:visibility="invisible"
android:clickable="false"
/>
</LinearLayout>
</RelativeLayout>
In the main activity, I've made a simple onClicklistener for Edit and Save button as shown below :
mEdit = (Button)findViewById(R.id.Prof_edit_btn);
mEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
mBatal.setVisibility(View.VISIBLE);
mBatal.setClickable(true);
mSave.setVisibility(View.VISIBLE);
mSave.setClickable(true);
mEdit.setVisibility(View.INVISIBLE);
}
});
mSave = (Button)findViewById(R.id.Prof_save_btn);
mSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
mEdit.setVisibility(View.VISIBLE);
mBatal.setVisibility(View.INVISIBLE);
mSave.setVisibility(View.INVISIBLE);
Toast.makeText(getApplicationContext(), "Data Anda berhasil disimpan", Toast.LENGTH_SHORT).show();
}
});
Well... As we can see from my layout xml, only EDIT button will be visible on the start, then SAVE and BATAL button will be visible when EDIT is clicked by user according to the code program within setonclick listener of EDIT button. And as soon as EDIT button is clicked it will be invisible.... The problems here are WHen I clicked EDIT button, only SAVE button will be visible and BATAL button will be visible when SAVE button is clicked, another problem that I'm facing now is EDIT button is not invisible at all when I click it.... So.. anyone can help me with this problem please...??? :'(
Thanks in advance....
Naaah... I found my own solution... Just set the visibility of SAVE btn and BATAL btn to GONE... And it's all done.... :-)
<Button
android:id="#+id/Prof_save_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
android:visibility="gone"<-----------=

I want to change the background image and TextView Color on click of a layout .The background color is chnaging properly but my textview color is not changing.Here is my XML code :
<RelativeLayout
android:id="#+id/flight_relative"
android:clickable="true"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_below="#+id/imgLogo"
android:layout_marginTop="5dp"
android:background="#drawable/button_effect"
android:gravity="center_vertical" >
<TextView
android:id="#+id/flight_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/flight_list_image"
android:layout_marginTop="10dp"
android:layout_toRightOf="#+id/flight_list_image"
android:text="#string/flight_tittle"
android:textColor="#152b72"
android:textSize="15dp"
android:textStyle="bold" />
<TextView
android:id="#+id/content_flight"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/flight_content"
android:layout_toRightOf="#+id/flight_list_image"
android:text="#string/flight_content"
android:textColor="#2f2f2f"
android:textSize="10sp" />
<ImageView
android:id="#+id/flight_arrow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/flight_content"
android:layout_alignParentRight="true"
android:src="#drawable/arrow" />
<ImageView
android:id="#+id/flight_list_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:padding="3dip"
android:src="#drawable/flight_icon" />
</RelativeLayout>
Code to chnage the textview color is :
flightRelative = (RelativeLayout )findViewById(R.id.flight_relative);
flightRelative.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
flight = (TextView)findViewById(R.id.flight_content);
flight.setTextColor(Color.WHITE);
}
});
What wrong i am doing please suggest me .For the first time it is not working on second time it is working
You should add this definitely working.I am also check it out...
flightRelative.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
TextView flight = (TextView)findViewById(R.id.flight_content);
flight.setTextColor(Color.parseColor("#FFFFFF"));
}
});
you should use
#Override
public void onClick(View arg0) {
flight = (TextView)flightRelative.findViewById(R.id.flight_content);
flight.setTextColor(Color.WHITE);
}
I believe it should work now.
I am using two buttons, one for next news and one for previous news. In my activity when I am on the first news my button should set the image with the grey image and when I move forward my previous news button should change from the grey image to the colored one. Similarly when I reach at the last news my next button should change to grey image.
This is my xml file.

if (newsId < newsListDetail.size() - 1) {
newsId++;
putDetailNewsinView(newsId);
if(newsId == 0)
btnNextNews.setBackgroundDrawable(getResources().getDrawable(

} else if (newsId == newsListDetail.size()) {
// btnNextNews.setVisibility(View.INVISIBLE);
btnNextNews.setBackgroundDrawable(getResources().getDrawable(

// btnNextNews.setBackgroundResource(R.drawable.disable_arrow_right);
btnNextNews.setEnabled(false);
}
}
}
Please help me out in this.
Thanks in advance.
I assume you have Methods which will be executed if the Button is pressed. Just use these and add Logic to change the Background of these Buttons to grey:
Give both Buttons an ID, you can access these Buttons with:
Button mybutton = (Button) findViewById(R.id.yourid);
Now you can do all kinds of things with your button, like changing the background.
edit:
The Problem could lay in the Pictures, but if i were you, i would set some breakpoints and debug step-by-step.
I hacked some code of mine to test this functionality, it works fine for me. Here is it:
package my.namespac;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class SomeTestProjectActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button)findViewById(R.id.btn_prevNews);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Button b = (Button)v;
v.setBackgroundDrawable(getResources().getDrawable(R.drawable.koala));
}
});
}
}
And the Layout-Xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/btn_prevNews"
android:layout_width="120sp"
android:layout_height="40sp"
android:layout_weight="0.5"
android:layout_marginRight="5sp"
android:background="#drawable/ic_launcher"
android:clickable="true" />
</LinearLayout>
