Cannot Resolve Method setVisibility(int)

I am attempting to have have a edittext box appear when a certain radiobutton in a group is checked. I am getting the error with setVisibility, and when running the error that it says is int cannot be dereferenced.
JAVA
public class MainActivity extends AppCompatActivity {
//Declared some variables here. One for each field in the form
ShareActionProvider mShareActionProvider;
String feedbackType;
String feedback;
String email;
String fName;
String lName;
String fAnswer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RadioGroup radiochoice=(RadioGroup) findViewById(R.id.radiochoice);
radiochoice.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId == R.id.RejectRadio) {
R.id.RejectResponse.setVisibility(View.VISIBLE);}
else if (checkedId == R.id.AcceptRadio) {
R.id.RejectResponse.setVisibility(View.INVISIBLE);}
}
});
}

You have to do this:
//Reference rejectResponse
EditText rejectResponse = (EditText) findViewById(R.id.RejectResponse);
//Change visibility
rejectResponse.setVisibility(View.INVISIBLE);

Android: stop scrolling when imageview is touched?

You cannot disable the scrolling of a ScrollView. You would need to extend to ScrollView and override the onTouchEvent method to return false when some condition is matched.
public class LockableScrollView extends ScrollView {
private boolean mScrollable=true;
public LockableScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
Override required methods and constructors
#Override
public boolean onTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
// if we can scroll pass the event to the superclass
if (mScrollable) return super.onTouchEvent(ev); //return mScrollable condition is false
/*
*Write your code here to implement your functionality like if you image view is touched
*/
// only continue to handle the touch event if scrolling enabled
return mScrollable; // mScrollable is always false at this point
// mScrollable flag may help you
//use it as a condition
default:
return super.onTouchEvent(ev);
}
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
// if we can scroll pass the event to the superclass
if (mScrollable) return super.onInterceptTouchEvent(ev);
// only continue to handle the touch event if scrolling enabled
return mScrollable; // mScrollable is always false at this point
default:
return super.onInterceptTouchEvent(ev);
}
}

switch to another activity with swipe is not working

My requirement :-
I have two activities..When I swipe it will go to another activity..
So,I have :--
MainActivity.java
public class MainActivity extends Activity {
private GestureDetectorCompat gestureDetectorCompat;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_getservice);
gestureDetectorCompat = new GestureDetectorCompat(this, new MyGestureListener());
}
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetectorCompat.onTouchEvent(event);
return super.onTouchEvent(event);
}
class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
//handle 'swipe left' action only
#Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
if(event2.getX() < event1.getX()){
//switch another activity
Intent intent = new Intent(
MainActivity.this, Join_form.class);
startActivity(intent);
finish();
}
return true;
}
}
}
and Join_form.java
public class Join_form extends Activity {
private GestureDetectorCompat gestureDetectorCompat;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gestureDetectorCompat = new GestureDetectorCompat(this, new MyGestureListener());
}
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetectorCompat.onTouchEvent(event);
return super.onTouchEvent(event);
}
class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
//handle 'swipe left' action only
#Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
if(event2.getX() > event1.getX()){
//switch another activity
Intent intent = new Intent(
Join_form.this, MainActivity.class);
startActivity(intent);
finish();
}
return true;
}
}
}

But I can not swipe the page. It is not going to the another page. Why it is happening?
Where is the problem?

Agree with #k3v1n4ud3. Let me just expand a bit since I can't really comment due to lack of karma.
With ViewPager (inside MainActivity.java) + MainFragment (Fragment)+ JoinForm (Fragment), you would be able to get away without having a listener for fling. It would just handle the swiping part automatically for you.
Just think about it like this: You have a brain (MainActivity w/ViewPager) and two arms (the first and second fragment you're implementing).
Create a MainActivity that would contain your ViewPager.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myViewPager = (ViewPager) findViewById(R.id.myViewPager);
//somehow fill the adapter
MyAdapter myAdapter = new MyAdapter(getSupportFragmentManager(), getApplicationContext()); //=== required as per the MyAdapter class
//set the adapter
myViewPager.setAdapter(myAdapter);
// display first fragment
myViewPager.setCurrentItem(0);
}
Create an Adapter that extends FragmentPagerAdapter (or FragmentStatePagerAdapter). It looks like this:
class MyAdapter extends FragmentPagerAdapter {
private final int[] titles = {R.string.main_activity_title, R.string.join_activity_title};
private final String[] fragments = {
MainFragment.class.getName(),
JoinFragment.class.getName()
};
private final Context ctx;
public MyAdapter(FragmentManager fm, Context ctx) {
super(fm);
this.ctx = ctx;
}
#Override
public CharSequence getPageTitle(int position) {
return ctx.getString(titles[position]);
}
#Override
public Fragment getItem(int position) {
return Fragment.instantiate(ctx, fragments[position]);
}
#Override
public int getCount() {
return titles.length;
}
}
(Optional) See those title thingys on top of each page, the ones you could click so you could fast forward to the other page? They're called tabhosts.
To use them, simply add a tabhost to your MainActivity layout and add this logic in MainActivity.java:
myViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// when user do a swipe the selected tab change
myTabHost.setSelectedNavigationItem(position);
}
});
//set titles
for (int i = 0; i < myAdapter.getCount(); i++) {
myTabHost.addTab(
myTabHost.newTab()
.setText(myAdapter.getPageTitle(i))
.setTabListener(this)
);
}
4. (Optional) Animations on 'fling'
So to animate when you switch fragments, you simple have to call this:
myViewPager.setPageTransformer(true, new DefaultTransformer());
And you can also customize it to your will.
I apologize if there are typos and other stuff. But this should cover majority of what you need.

You probably should change the architecture, transform your 2 activities into fragment and place them inside a viewPager. The viewPager will handle the sliding part for you.

how to attach a listener to a radio button

I have an activity that displays various radiobuttons. The radiobuttons are grouped in radiogroups. I want some of the radiobutton to disappear when a certain radiobutton is checked. eg when the incident button is checked the fall, trip and illness radiobutton disappear. how can i achieve this?
I have the foolowing code but need to somehow attach a listener to the incident button.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reportsomethinglayout);
resolution = (EditText)findViewById(R.id.editTextresolution);
// resolution.setInputType(InputType.TYPE_NULL);
// showSoftKeyboard(resolution);
accident = (RadioButton)findViewById(R.id.radioButtonaccident);
incident = (RadioButton)findViewById(R.id.radioButtonincident);
concern = (RadioButton)findViewById(R.id.radioButtonconcern);
fall = (RadioButton)findViewById(R.id.radioButtonfall);
trip = (RadioButton)findViewById(R.id.radioButtonTrip);
illness = (RadioButton)findViewById(R.id.radioButtonillness);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radioButtonaccident:
if (checked)
Log.e(TAG, "accident radiobutton checked");
break;
case R.id.radioButtonincident:
if (checked)
Log.e(TAG, "incident radiobutton checked");
fall.setVisibility(View.GONE);
trip.setVisibility(View.GONE);
illness.setVisibility(View.GONE);
break;
}
}

try like this:-
RadioGroup group = (RadioGroup) findViewById(R.id.radioGroup1);
group.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
// TODO Auto-generated method stub
if(radiobutton1.isChecked()) {
fall.setVisibility(View.GONE);
trip.setVisibility(View.GONE);
illness.setVisibility(View.GONE);
} else if(radiobutton2.isChecked()) {
}
}
});

You can set a listener on a RadioGroup with setOnCheckedChangeListener. The onCheckedChanged callback receives the ID of the newly checked button in the checkedId parameter.
In your case, just add an ID to your radio group (in order to retrieve it from your code)
<RadioGroup
android:id="#+id/category_group"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
And use the following code:
RadioGroup categoryGroup = (RadioGroup) findViewById(R.id.category_group);
categoryGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch(checkedId) {
case R.id.radioButtonincident:
// 'Incident' checked
fall.setVisibility(View.GONE);
trip.setVisibility(View.GONE);
illness.setVisibility(View.GONE);
break;
case R.id.radioButtonaccident:
// 'Accident' checked
break;
case R.id.radioButtonconcern:
// 'Concern' checked
break;
}
}
});

How to make Views with an Invisible attribute 'Visible' after clicking a button

I have several Views, text views, and a button that have the android:visibility="invisible" attribute. My goal is to click a button that resides above these 'invisible' widgets, so that these widgets will become visible. I created another java class called 'VisibilityActivity.java" and tried the following method. But for some reason when I run the app, the button doesn't do anything. I don't know what I'm missing.
Here's the code:
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class VisibilityActivity extends Activity {
private View mVictim;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_property3);
mVictim = findViewById(R.id.horizontalRule1);
mVictim = findViewById(R.id.TextView03);
mVictim = findViewById(R.id.horizontalRule2);
Button submitRating = (Button) findViewById(R.id.submitRatingButton);
submitRating.setOnClickListener(mVisibleListener);
}
OnClickListener mVisibleListener = new OnClickListener() {
public void onClick(View v) {
mVictim.setVisibility(View.INVISIBLE);
}
};
}
Here is the xml:

Thanks. Help would be greatly appreciated!

I am updating user936414's answer.
OnClickListener mVisibleListener = new OnClickListener() {
public void onClick(View v) {
if( mText.getVisibility() == View.INVISIBLE )
mText.setVisibility(View.VISIBLE);
else
mText.setVisibility(View.INVISIBLE);
if( mRule1.getVisibility() == View.INVISIBLE )
mRule1.setVisibility(View.VISIBLE);
else
mRule1.setVisibility(View.INVISIBLE);
if( mRule2.getVisibility() == View.INVISIBLE )
mRule2.setVisibility(View.VISIBLE);
else
mRule2.setVisibility(View.INVISIBLE);
}
};
Also you might want to experiment with View.GONE.

findViewById(R.id.ratingBar3).setVisibility(View.VISIBLE);
findViewById(R.id.saveContinueButton3).setVisibility(View.VISIBLE);
you made it invisible view invisible again.. try the above code

Try
public class VisibilityActivity extends Activity {
private TextView mText;
private View mRule1, mRule2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_property3);
mText= (TextView)findViewById(R.id.horizontalRule1);
mRule1 = findViewById(R.id.TextView03);
mRule2 = findViewById(R.id.horizontalRule2);
Button submitRating = (Button) findViewById(R.id.submitRatingButton);
submitRating.setOnClickListener(mVisibleListener);
}
OnClickListener mVisibleListener = new OnClickListener() {
public void onClick(View v) {
mText.setVisibility(View.VISIBLE);
mRule1.setVisibility(View.VISIBLE);
mRule2.setVisibility(View.VISIBLE);
}
};
}

Button submitRating = (Button) findViewById(R.id.submitRatingButton);
submitRating.setOnClickListener(new View.onClickListener)
{
#Override
public void onClick(View v)
{
//Insert your code here
}
}
