ViewFlipper animation in same Activity

I have this screen.
And want to convert it to this.
I hope you understand what I am trying to do. Here is my xml code.
<?xml version="1.0" encoding="utf-8"?>

and my activity
public class MainActivity extends AppCompatActivity implements View.OnClickListener{

Button signUpButton;
ViewFlipper viewFlipper;
#Override
public void onCreate(Bundle instanceState) {
super.onCreate(instanceState);
setContentView(R.layout.content_main);

loginButton.setTag(true);
signUpButton = (Button)findViewById(R.id.bt_signup);

loginButton.setOnClickListener(this);
signUpButton.setOnClickListener(this);
updateTheViewBasedOnTag();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bt_login:
loginButton.setTag(true);
updateTheViewBasedOnTag();
viewFlipper.startFlipping();
break;
case R.id.bt_signup:
signUpButton.setTag(true);
updateTheViewBasedOnTag();
break;
}
}
private void updateTheViewBasedOnTag() {
if((boolean)loginButton.getTag())
{
loginButton.setBackground(getDrawable(R.drawable.selected_background));
signUpButton.setBackground(getDrawable(R.drawable.normal_background));
}else
{
loginButton.setBackground(getDrawable(R.drawable.selected_background));
loginButton.setBackground(getDrawable(R.drawable.normal_background));
}
}
}
The
viewFlipper.startFlipping();
doesn't seem to work correctly. I don't click the signup button but still the sign up for is shown. Also, the clicking of the buttons don't respond
What's wrong?
Thanks,
Theo.

I am just trying to guess what is wrong with your code. You are setting the tag to true for one button and forgot to set the false for other button.
switch (v.getId()) {
case R.id.bt_login:
loginButton.setTag(true);
signUpButton.setTag(false);
updateTheViewBasedOnTag();
viewFlipper.startFlipping();
break;
case R.id.bt_signup:
signUpButton.setTag(true);
loginButton.setTag(false);
updateTheViewBasedOnTag();
break;
}

Changing Activities through a button and display xml

I am very new at android development, and I am trying to make an app which has 4 buttons in its main activity and when I click on one of its button it takes me to another activity and displays its xml file, what should I write in the 2nd activity? Here is my code so far.

My answer as a checklist:
1.- If you are using android studio you should create 2nd activity with the assistant so you dont get into more complications.
The 2nd activity must have an xml file and a class file.
2.- You should add android:onClick propertie for your button in the xml file on the activity.
3.- Your 2nd activity must have an onCreate method in the class file to fill the contents of the 2nd activity.
3b.- You can leave onCreate with default content but your xml file must then have al the info of your textviews.
I can elaborate further if needed.

Let's say you have two activities : Activity1.java and Activity2.java.
to start Activity2 from Activity1 just do :
final Intent intent = new Intent(this, Activity2.class);>startActivity(intent)
If you want to start activity on button click you have to write this codein an onClickListener. To do that, write the following attribute in your button definition in Activity1 xml file.
android:onCLick="onButtonClick"
Then in your activity write the following listener :
public void onButtonClick(final View v) {
// put your intent here
}

This code help you ....
public class MainActivity extends AppCompatActivity {
Button btn1 ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.btn1);
final String name = editText.getText().toString();
button.setOnClickListener(new View.OnClickListener() {//when your btn1 button press
public void onClick(View v) {
Intent intent = new Intent(this, Activity2.class);//this is call your second activity
startActivity(intent);//start activity
}
});
}
}

First of all, you must get your Button id from your xml. Or you will get NullPointerException so change your onCreate like this.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (Button)findViewById(R.id.one); //This line
btn2 = (Button)findViewById(R.id.two); //and this line
btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
}
And if you want to call intent with Class, you can see this solution
OR
You can simply call another activity like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (Button)findViewById(R.id.one); //This line
btn2 = (Button)findViewById(R.id.two); //and this line
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(firstActivity.this, secondActivity.class));
}
});
}

findViewById doesn't find my view

This is my java:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_starting_point);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
counter = 0;
add = (Button) findViewById(R.id.add_butt);
sub = (Button) findViewById(R.id.sub_butt);
display = (TextView) findViewById(R.id.tv_text);
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
counter++;
display.setText("Your Total is " + counter);
}
});
and this is my xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.myfirstapp.StartingPoint$PlaceholderFragment" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Your Total is 0"
android:textSize="40sp"
android:layout_gravity="center"
android:id="#+id/tv_text" />
<Button
android:layout_width="250dp"
android:layout_height="wrap_content"
android:text="Add 1"
android:layout_gravity="center"
android:id="#+id/add_butt" />
<Button
android:layout_width="250dp"
android:layout_height="wrap_content"
android:text="Sub 1"
android:layout_gravity="center"
android:id="#+id/sub_butt" />
</LinearLayout>
I get a NullPointerExeption error when I try to add the listeners, because the findViewById method returns null on all the views... I think that everything is in place. All the views are in the XML and they have the proper ID's, so what did i do wrong?

You are trying to findViewById of views that are located in the Fragment.
Try moving this code to your PlaceholderFragment class (OnCreateView)

Fragment UI components null TextViews

New android developer here. I am trying to create a dynamic UI that loads based on the users selection of a RadioGroup. Based on their selection, one of 3 possible fragments will be loaded into a LinearLayout section. This is my first attempt at my own sample problem that is not just a walk-through tutorial. Here is the main activity:
public class BaseConverter extends Activity {
RadioGroup convert;
Fragment toFragment;
RadioGroup toRadioGroup = null;
TextView inputDisplay = null;
TextView outputDisplay = null;
TextView resultTitle = null;
#Override
public void onCreate(Bundle sIS) {
super.onCreate(sIS);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.setContentView(R.layout.base_converter);
convert = (RadioGroup) this.findViewById(R.id.bc_convert_group);
convert.setOnCheckedChangeListener(new ConvertListener());
FragmentManager fm = getFragmentManager();
FragmentTransaction converterFragment = fm.beginTransaction();
ConvertEmptyFragment emptyTo = new ConvertEmptyFragment();
converterFragment.replace(R.id.bc_converter_fragment, emptyTo);
converterFragment.commit();
FragmentTransaction toFragment = fm.beginTransaction();
ConvertEmptyFragment emptyConverter = new ConvertEmptyFragment();
toFragment.replace(R.id.bc_to_fragment, emptyConverter);
toFragment.commit();
}
#Override
public void onResume() {
convert.clearCheck();
super.onResume();
}
#Override
public void onPause() {
convert.clearCheck();
super.onPause();
}
// I put a little null check so you can see how I'm trying to access the TextViews and what results
public void updateUIComponents(){
View converterView = this.findViewById(R.id.bc_converter_fragment);
inputDisplay = (TextView)converterView.findViewById(R.id.bc_display_input);
outputDisplay = (TextView)converterView.findViewById(R.id.bc_display_output);
if (inputDisplay == null){
Log.d("BaseConverter", "inputDisplay == null");
} else {
Log.d("BaseConverter", "inputDisplay != null");
}
}
class ConvertListener implements OnCheckedChangeListener {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
Fragment toFragment;
Fragment converterFragment;
switch (checkedId) {
case R.id.bc_convert_binary:
toFragment = new ConvertRBFragmentBinary();
converterFragment = new ConverterFragmentBinary();
break;
case R.id.bc_convert_decimal:
toFragment = new ConvertRBFragmentDecimal();
converterFragment = new ConverterFragmentDecimal();
break;
case R.id.bc_convert_hex:
toFragment = new ConvertRBFragmentHex();
converterFragment = new ConverterFragmentHex();
break;
default:
toFragment = new ConvertEmptyFragment();
converterFragment = new ConvertEmptyFragment();
break;
}
FragmentManager fm = getFragmentManager();
FragmentTransaction converterTransaction = fm.beginTransaction();
converterTransaction.replace(R.id.bc_converter_fragment, converterFragment);
converterTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
converterTransaction.commit();
FragmentTransaction toTransaction = fm.beginTransaction();
toTransaction.replace(R.id.bc_to_fragment, toFragment);
toTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
toTransaction.commit();
updateUIComponents();
}
}
So, based on what a user chooses, the proper fragments will be loaded into the respective LinearLayout sections. However, now I want to implement the business logic of the fragments (which is just integer base conversion; i.e. binary number to decimal...) but when I try to access the TextViews, as seen in the updateUIComponents method, I get null pointers. What am I missing?
Here's the ConverterFragmentBinary class for reference:
public class ConverterFragmentBinary extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle sIS){
View v = inflater.inflate(R.layout.converter_fragment_binary, container, false);
return v;
}
}
and its respective xml layout for reference:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ImageView
android:id="#+id/bc_binary_converter_logo"

Thanks in advance and sorry for the long code blocks but I figured it was better to include more than less.

Also, you should inflate your Fragments layout to bring it from your XML to your Java code instead of simply referring it using findViewById() method.
So instead of doing this,
View converterView = this.findViewById(R.id.bc_converter_fragment);
Do this inside your onCreateView method of the fragment,
View converterView = infalter.inflate(R.id.bc_converter_fragment,null);
updateUIComponents(converterView);//call this methid and pass your view
new method looks like this,
public void updateUIComponents(View converterView){
inputDisplay = (TextView)converterView.findViewById(R.id.bc_display_input);
outputDisplay = (TextView)converterView.findViewById(R.id.bc_display_output);
if (inputDisplay == null){
Log.d("BaseConverter", "inputDisplay == null");
} else {
Log.d("BaseConverter", "inputDisplay != null");
}
}

android coding force close

here is the code that is giving the force close error running on avd
public class MainActivity extends Activity {
Button magic;
TextView display;
int random;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
magic=(Button)findViewById(R.id.magic);
display=(TextView)findViewById(R.id.textView1);
magic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
random = (int)Math.ceil(Math.random()*100);
display.setText("your number is"+random);
}
});
}
}
here is the code i am using even if random function or settext is not used application force closes please help

the xml file is given where the single waring is related to the textview1 when hard coded
since the text is about to change whether it is good to set it on string.xml or hard code it ?????

For what purpose you are using following code.
**<android.widget.Space
android:id="#+id/space1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"

This seems not available.. its working fine in the ICS devices.. but not working in Gingerbread devices.. I think that's the unusable code...
