i make a math keyboard inside my programm.
Than i did editText, where will add a text from my keyboard
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow>
<Button
android:theme="#style/Widget.AppCompat.Button.Colored"
android:layout_weight="1"
android:gravity="center"
android:id="#+id/buttonClick"
android:layout_width="10dp"
android:layout_height="45dp"
android:text="#string/Calc"/>
<EditText
android:layout_weight="1"
android:id="#+id/editGraphText"
android:layout_width="200dp"
android:layout_height="45dp"
android:inputType="textPersonName"
android:text=""/>
<Button
android:id="#+id/buttonClear"
android:layout_width="45dp"
android:layout_height="45dp"
android:gravity="center"
android:text="#string/Clear" />
</TableRow>
</TableLayout>
Then i need to hide my keyboard and open it again.
When i hide my keyboard and open it again, my code does't work.
I checked buttons. Button is work, but editText did't change.
Here code on java
keyBoard = (LinearLayout) view.findViewById(R.id.keyBoard);
editText = (EditText) view.findViewById(R.id.editGraphText);
editText.setInputType(InputType.TYPE_NULL);
buttonSin = (Button) view.findViewById(R.id.graphSin);
buttonCos = (Button) view.findViewById(R.id.graphCos);
buttonTan = (Button) view.findViewById(R.id.graphTan);
buttonCot = (Button) view.findViewById(R.id.graphCot);
buttonAsin = (Button) view.findViewById(R.id.graphAsin);
buttonAcos = (Button) view.findViewById(R.id.graphAcos);
buttonAcot = (Button) view.findViewById(R.id.graphAcot);
buttonAtan = (Button) view.findViewById(R.id.graphAtan);
buttonMultiply = (Button) view.findViewById(R.id.graphMultiply);
buttonSum = (Button) view.findViewById(R.id.graphSum);
buttonDegree = (Button) view.findViewById(R.id.graphDegree);
buttonMinus = (Button) view.findViewById(R.id.graphMinus);
buttonDivizion = (Button) view.findViewById(R.id.graphDivizion);
buttonLog = (Button) view.findViewById(R.id.graphLog);
buttonLg = (Button) view.findViewById(R.id.graphLg);
buttonPi = (Button) view.findViewById(R.id.graphPi);
buttonE = (Button) view.findViewById(R.id.graphE);
buttonLeftBracket = (Button) view.findViewById(R.id.graphLeftBracket);
buttonLeftSquareBracket = (Button) view.findViewById(R.id.graphLeftSquareBracket);
buttonRightSquareBracket = (Button) view.findViewById(R.id.graphRightSquareBracket);
buttonRightBracket = (Button) view.findViewById(R.id.graphRightBracket);
buttonOne = (Button) view.findViewById(R.id.graphOne);
buttonTwo = (Button) view.findViewById(R.id.graphTwo);
buttonThree = (Button) view.findViewById(R.id.graphThree);
buttonFour = (Button) view.findViewById(R.id.graphFour);
buttonFive = (Button) view.findViewById(R.id.graphFive);
buttonSix = (Button) view.findViewById(R.id.graphSix);
buttonSeven = (Button) view.findViewById(R.id.graphSeven);
buttonEight = (Button) view.findViewById(R.id.graphEight);
buttonNine = (Button) view.findViewById(R.id.graphNine);
buttonZero = (Button) view.findViewById(R.id.graphZero);
buttonModule = (Button) view.findViewById(R.id.graphModule);
buttonX = (Button) view.findViewById(R.id.graphX);
buttonY = (Button) view.findViewById(R.id.graphY);
buttonLn = (Button) view.findViewById(R.id.graphLn);
buttonClear = (Button) view.findViewById(R.id.graphDelete);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
keyBoard.setVisibility(View.VISIBLE);
}
});
buttonSin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finalText += "sin(";
editText.setText(finalText);
}
});
buttonCos.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finalText += "cos(";
editText.setText(finalText);
}
});
buttonTan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finalText += "tan(";
editText.setText(finalText);
}
});
buttonCot.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finalText += "cot(";
editText.setText(finalText);
}
});
When i want to hide my keyboard i use this in my activity
#Override
public void onBackPressed() {
LinearLayout keyBoard = (LinearLayout) findViewById(R.id.keyBoard);
if (keyBoard.getVisibility() == View.INVISIBLE) {
Fragment fragment = null;
Class fragmentClass = null;
fragmentClass = GraphActivity.class;
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.container, fragment).commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
} else {
keyBoard.setVisibility(View.INVISIBLE);
}
}
Other clickListener inside code, here is a part of code, i did't copy every clickListener.
How i can make to work my code?
I need to hide my keyboard and I want to open it again, but it did't work.
Where is my mistake?

this is the design

You can create a application with Navigation drawer Activity here you can see custom layout inside drawer layout and inside layout you can set any type of widgets as button, TextView and any type what ever you want.

In xml file, my drawer menu items (LinearLayout and Buttons) were over my main LinearLayout. I just cut-paste it under the main LinearLayout and it helped.
here is the updated xml file of my project, hope will help someone.

And this is the XML. The add1, add2, add3 and submit ImageButtons are all in a ScrollView.
When I press the add1 ImageButton, I want the add2 and site2 ImageButtons to become visible but instead, it throws the following error.
Motion event has invalid pointer count 0; value must be between 1 and 16.
What am I doing wrong?
PS: All the findViewById() calls are in the onClick() method because a NullPointerExeption is thrown if I call them in the onCreate().

Those findViewByIdcalls in onClickdon't make sense. Not sure why you are getting a null pointer exception calling them in onCreate.onClick is never called in this instance because nothing in the creation of the Activity is assigning the buttons to look at your onClick method; the buttons will default to having no listener assigned. It also doesn't look like a good idea to use the Activity as the onClickListener as well.
Your code should look something like this:
public class AddActivity extends Activity {
// https://source.android.com/source/code-style.html
// info -> mInfo; non-public, non-static field!
String[] mInfo = new String[11];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_layout);
TextView keyString = (TextView)findViewById(R.id.keyString);
TextView site1 = (TextView)findViewById(R.id.site1);
TextView site2 = (TextView)findViewById(R.id.site2);
TextView site3 = (TextView)findViewById(R.id.site3);
Button submit = (Button)findViewById(R.id.submit);
ImageButton add1 = (ImageButton)findViewById(R.id.add1);
ImageButton add2 = (ImageButton)findViewById(R.id.add2);
ImageButton add3 = (ImageButton)findViewById(R.id.add3);
add1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
add2.setVisibility(View.VISIBLE);
site2.setVisibility(View.VISIBLE);
}
});
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
submitEntry(mInfo);
}
});
}

The findViewById() calls and especially the setOnClickListener() calls should have been inside the onCreate(). With setOnClickListener() inside the onClick() i doubt the onClick was ever called.
We would need more logs to find the exact issue.

I have added an imageswitcher to my register fragment, when the user select his/her gender the image changes but the image shown is too big and I cant scale it.

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);
}
};
}

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
}
}
