Multiple Radio group in a single Activity - java

I'm Developing an android app in which the Questionnaire activity contains radio buttons for every question.And I've designed the activity in Linear layout.So now i wanted to check whether the user as answered all Questions.The problem I'm facing is in the public void OnClick(View v)help me in modifying the java code.
<RadioGroup
android:id="#+id/Mquestion1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="#+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_1_rb1" />
<RadioButton
android:id="#+id/radioButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_1_rb2" />
<RadioButton
android:id="#+id/radioButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_1_rb3" />
</RadioGroup>
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_2_view"
android:textAppearance="?android:attr/textAppearanceSmall" />
<RadioGroup
android:id="#+id/Mquestion2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="#+id/radioButton4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_2_rb1" />
<RadioButton
android:id="#+id/radioButton5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_2_rb2" />
<RadioButton
android:id="#+id/radioButton6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_2_rb3" />
</RadioGroup>
<TextView
android:id="#+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_3_view"
android:textAppearance="?android:attr/textAppearanceSmall" />
<RadioGroup
android:id="#+id/Mquestion3"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="#+id/radioButton7"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_3_rb1" />
<RadioButton
android:id="#+id/radioButton8"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_3_rb2" />
<RadioButton
android:id="#+id/radioButton9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/MQ1_3_rb3" />
</RadioGroup>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="44dp" >
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:onClick="OnClickListener"
android:text="#string/MQ1_next" />
</RelativeLayout>
</LinearLayout>
Here is the java code
public class ManagerQuestionnaire1 extends Activity
{
Button next;
RadioGroup rg1;
RadioGroup rg2;
RadioGroup rg3;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_manager_questionnaire1);
final RadioGroup rg1=(RadioGroup)findViewById(R.id.Mquestion1);
final RadioGroup rg2=(RadioGroup)findViewById(R.id.Mquestion2);
final RadioGroup rg3=(RadioGroup)findViewById(R.id.Mquestion3);
Button next=(Button)findViewById(R.id.button1);
next.setOnClickListener(new View.OnClickListener()
{
public void OnClick(View v) \\The error I'm getting here is REMOVE method'OnClick'
{
if((rg1.getCheckedRadioButtonId()!=R.id.radioButton1 || rg1.getCheckedRadioButtonId()!=R.id.radioButton2 || rg1.getCheckedRadioButtonId()!=R.id.radioButton3)||(rg2.getCheckedRadioButtonId()!=R.id.radioButton4 || rg2.getCheckedRadioButtonId()!=R.id.radioButton5 || rg2.getCheckedRadioButtonId()!=R.id.radioButton6)||(rg3.getCheckedRadioButtonId()!=R.id.radioButton7 || rg3.getCheckedRadioButtonId()!=R.id.radioButton8 || rg3.getCheckedRadioButtonId()!=R.id.radioButton9))
{
AlertDialog alert= new AlertDialog.Builder(ManagerQuestionnaire1.this).create();
alert.setTitle("Exception:Complete the Questions");
alert.setMessage("Please ensure all Questions are answered");
}
else
{
Intent intent = new Intent(ManagerQuestionnaire1.this, ManagerQuestionnaire2.class);
startActivity(intent);
}
}
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
}
});
}

It is always recommended to user radiobuttons inside a radioGroup
like this :
<RadioGroup
android:id="#+id/question1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<RadioButton
android:id="#+id/radio0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="RadioButton" />
<RadioButton
android:id="#+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton" />
<RadioButton
android:id="#+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton" />
</RadioGroup>
<RadioGroup
android:id="#+id/question2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<RadioButton
android:id="#+id/radio3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="RadioButton" />
<RadioButton
android:id="#+id/radio4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton" />
<RadioButton
android:id="#+id/radio5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton" />
</RadioGroup>
Now whenever you want to see which answer is selected corrosponding to which radio group you can do something like this :
RadioGroup question1 = (RadioGroup) findViewById(R.id.question1);
String answer1 = ((RadioButton) findViewById(question1.getCheckedRadioButtonId())).getText().toString();
Congrates ! you got the answer here

change your xml file here
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RadioGroup
android:id="#+id/radio"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_1_view"
android:textAppearance="?android:attr/textAppearanceSmall" />
<RadioButton
android:id="#+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_1_rb1" />
<RadioButton

<RadioButton
android:id="#+id/radioButton5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_2_rb2" />
<RadioButton
android:id="#+id/radioButton6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_2_rb3" />
<TextView
android:id="#+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_3_view"
android:textAppearance="?android:attr/textAppearanceSmall" />
<RadioButton
android:id="#+id/radioButton7"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<RadioButton
android:id="#+id/radioButton8"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_3_rb2" />
<RadioButton
android:id="#+id/radioButton9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MQ1_3_rb3" />
</RadioGroup>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="44dp" >
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="MQ1_next" />
</RelativeLayout>
and in your java class define id for radiogroups.

I tried your code and I had to delete some stuff from your XML file because it was creating some bugs. It might be related to me but here's your XML I was able to use:
But please do not change your XML file before trying the solution below. If it still doesn't work, you should consider the elements I removed.

Next I created your Project2Activity java class and activity2 (pretty much empty since you gave no info about it).
So when trying to run your application you get the following error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.application.so/com.example.application.so.Project2Activity}: java.lang.NumberFormatException: For input string: ""
and it is at :
at com.example.application.so.Project2Activity.onCreate(Project2Activity.java:24)
now if we consider this lines 23 and 24:
String value=pek.getText().toString(); // line 23
final int pekerja=Integer.parseInt(value); // line 24
The error is that you are trying to read (line 23) your editText Value at the creation of the activity, at that time, your editText is still blank which means value will be equal to "" (empty string).
What you want to do instead is to put your lines from 22 to 33 (the ones below) in a button click event, I tried putting them in your button 1 click event and your app doesn't crash any more:
EditText pek=(EditText)findViewById(R.id.editText1);
String value=pek.getText().toString();
final int pekerja=Integer.parseInt(value);
EditText lam=(EditText)findViewById(R.id.editText2);
String value1=lam.getText().toString();
final int lama=Integer.parseInt(value1);
EditText up=(EditText)findViewById(R.id.editText3);
String value2=up.getText().toString();
final int upah=Integer.parseInt(value2);
EditText jum=(EditText)findViewById(R.id.editText4);
String value3=jum.getText().toString();
final int jumlah=Integer.parseInt(value3);
So to summarize, the problem is that you are extracting empty strings from your editTexts and trying to make integers out of them. Instead try making that all reading and integer extracting process on the click of a button where your really need these inputs. just like get the inputs and the final moment.
You should pay attention to your logcat (error messages), it is quite helpful.
What you can also do is to verify that your editTexts are not empty while trying to extract strings from them and raise exception or Toast if they are empty. Nothing too complicated just something like:
if (value.equals("")):
// editText is empty so do something
You can refer to this link for further understanding of how to know when an editText is empty.

How to RadioButton get selected

I have an API and there is a value of broadcast and the options are public, private, logged in and unlisted. I want a radiobutton to be selected itself as public if broadcast is public.
This is my XML code:
<TextView
android:textColor="#060606"
android:layout_marginTop="10dp"
android:textSize="15sp"
android:text="Broadcast Options"
android:id="#+id/broadcast_head"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioGroup
android:orientation="vertical"
android:id="#+id/radio_group_broadcast"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:textSize="16sp"
android:text="Public"
android:id="#+id/radio_button_public"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Private"
android:id="#+id/radio_button_private"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Unlisted"
android:id="#+id/radio_button_unlisted"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Logged Only"
android:id="#+id/radio_button_logged_only"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RadioGroup>
</TextView>
and this is my Java code;
I don't know whether this code is correct or not.
rbPub = (RadioButton)findViewById(R.id.radio_button_public);
rbPri = (RadioButton)findViewById(R.id.radio_button_private);
rbUnl = (RadioButton)findViewById(R.id.radio_button_unlisted);
rbOnl = (RadioButton)findViewById(R.id.radio_button_logged_only);
radioGroup1 = (RadioGroup) findViewById(R.id.radio_group_broadcast);
VideoDetail videoDetailBroadcast = null; //this is the problem, can't fix(null)
if (videoDetailBroadcast.isPublic()) {
rbPub.setChecked(true);
}
else if (videoDetailBroadcast.isPrivate()) {
rbPri.setChecked(true);
}
else if (videoDetailBroadcast.isUnlisted()) {
rbUnl.setChecked(true);
}
else if (videoDetailBroadcast.isLoggedOnly()) {
rbOnl.setChecked(true);
}
You should should initialize videoDetailBroadcast that way : VideoDetail videoDetailBroadcast = new VideoDetail()

TextView text animation is restarted if the text is changed in another TextView

In TextView1 text animation runs from right to left, and in TextView2 constantly changing text. The problem is that when I perform TextView2.setText ( "...") in the text animation TextView1 restarted. Is it possible to prevent the restart of the animation?
XML code TextView1:
<TextView
android:id="#+id/artistAlbum"
android:layout_width="wrap_content"
android:layout_height="24dp"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever"
android:paddingTop="2dp"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="text text text text text text text"
android:textSize="14sp" />
Java code initialization TextView1:
final TextView textView1 = (TextView) rootView.findViewById(R.id.textView1);
textView1.setSelected(true);
XML code TextView2:
<TextView
android:id="#+id/seekSongDuration"
android:layout_width="wrap_content"

Thanks in advance.
Try to wrap your TextView1 with LinearLayout.
Check Activity class TextView object and its assign id.

Crash's trying to find view

I have a slight problem that I have been stuck on. I have narrowed it down and it seems that my application is crashing on create when i am trying to find a text view. I do not understand why, maybe i have been looking at this to long and dont see the obvious.
Any help would be appreciated.
Thanks.

There are two possible things possible. Either you want all Textviews or all EditText.
If you want all Textview then replace all your EditTextin java file with Textview.
Textview fullName;
fullName = (Textview )findViewById(R.id.personsNameTv);
If you want all EditText then replace all Textview in xml with EditText.
<EditText
android:id="#+id/personsNameTv"
.../>
In XML you are using Text-view and in java file you define it Edit-text
<TextView
android:id="#+id/personsNameTv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fullName"
android:textColor="#FFFFFF"
android:textSize="15sp" />
Replace with
<EditText
android:id="#+id/personsNameTv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fullName"
android:textColor="#FFFFFF"
android:textSize="15sp" />

don't work onClick in buttons at list_view height = match_parent

I think because my ListView is set to layout_height="match_parent", the Buttons are not called onClick method.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if(convertView == null) {
Log.d(TAG_DEBUG,"0");
} else{
Button button1 = (Button) convertView.findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG_DEBUG, "TEST");
}
});
}
return super.getView(position, convertView, parent);
}
