How to position an ImageView in the same place in different screen sizes?

I been working on a simple android app that calculates a person's Body Mass Index, I have all the features working but positioning the arrow in the right place in the color bar corresponding to the user's screen size is what Im stuck on. I have it working by setting the X and Y values of the arrow ImageView but obviously the place of the arrow changes when i test my application in different screen sizes even though im coverting a dp value to pixels. How can I position the arrow ImageView so that it stays the same in different screen sizes?

Add Linearlayout as subparent of childview,use its orientation and gravity attribute you can easily get the design in more optimize way and suitable for everyscreen size.
here i have used RelativeLayout as Parent and LinearLayout as sub-parent of childview.

Try to avoid too much margin top and bottom.

Checkbox if condition?

so I have an android app with 2 Activities
1 - Main
2 - Second
Main activity has 1 single checkbox in a RelativeLayout I want to know how to use the checkbox to make a condition where if the check box is checked I want to make the ImageView = VISIBLE and the TextView = GONE in the Second activity and vice versa if its unchecked.
I have tried to use shared preferences and also intent but I keep messing up somewhere where either the checkbox wont matter or the screen just ends up showing blank. One other thing is that in Main activity I have a button that has onClick and already has an intent. I just want to know how to create the if condition with the checkbox for the Second activity. Sadly I would post my entire code but I have scrambled it up so bad trying to figure this out its all over the place and doesn't make sense anymore.
ok I tried to a few things, tried a posted answer but atleast I was able to clean up the code enough to share now but it messes up really badly and closes the app, sorry for any weird formatting, new to this

If you open the second activity from the main you can put the isChecked value in the intent else in this simple case make the value static

how to make Relative layout onclick work?

I have a Relative layout as:
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
I want my relative layout to perform onCLickListener but does not work.
I am able to do the setonclicklistener but it works only with the textview part and not for the image.
btniPay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//for ipay
}
});
This works for the text part only but not for the image. Any idea what I might be missing.

Alternatively, you can add android:clickable="false" in your button xml attribute.
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:clickable="false"
android:textColor="#ffffff" />
</RelativeLayout>

may be you can find some good example thats use with imageview and buttons but the easy way i did it by using adding TextView instead of images and buttons.
<RelativeLayout
android:id="#+id/layout1"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:clickable="true"
android:gravity="right">
<TextView
android:id="#+id/englishheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/urduheading1"
android:text="English text"
android:textColor="#ffffff"
android:textSize="15sp" />
<TextView
android:id="#+id/urduheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="15dp"
android:text="urdu text1"
android:textColor="#ffffff"
android:textSize="16sp" />
<View
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_alignParentBottom="true"
android:layout_marginTop="8dp"
android:background="#ffffff" />
</RelativeLayout>
Here is java code to perform onClick.
RelativeLayout layout1 = (RelativeLayout) view.findViewById(R.id.layout1);
layout1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something
}
});

see my code easily run change your code:
.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:id="#+id/btn"
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/ic_launcher"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
</RelativeLayout>
.java file
public class MainActivity extends Activity {
TextView tv;
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView) findViewById(R.id.tv);
btn = (Button) findViewById(R.id.btn);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "text", Toast.LENGTH_SHORT).show();
}
});
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "button", Toast.LENGTH_SHORT).show();
}
});
}
}

Just mark android:clickable="true" in your RelativeLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_id"
android:clickable="true">
Using ButterKnife lib make bind here:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_xml_name);
ButterKnife.bind(this);
}
#OnClick(R.id.activity_id)
void onActivityClick() {
// do smth ...
}

final Dialog dialog = new Dialog(Splash.this);
dialog.setContentView(R.layout.version_update);
dialog.setTitle(getString(R.string.alert_title));

dialog.show();
}

android:fillViewport="true" in ScrollView solved my problem. Now its scrolling even inside dialog.

You can use simply below code on ScollView. it's working fine.
<ScrollView>
<LinearLayout android:orientation="vertical"
android:scrollbars="vertical"
android:scrollbarAlwaysDrawVerticalTrack="true">

</ScrollView>

Dynamic View not being created in proper place. Overlapping previous view. Android

I am new to Android so I've been trying to tweak around for the past couple days but am stuck at this part. For my app, I'm trying to input a Button "Add More" which inflates a view to help incorporate user input but I'm running into issues. I looked around and I used his source code to help with my issue but I am running into the problem that my inflated xml layout is overlapping my previous set-up layout.
This is the layout that I have setup for my new_class_container file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parentView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true"
android:orientation="vertical"
android:background="#drawable/gradient_gray">
<!-- Class Name -->
<TextView
android:id="#+id/register_class_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/write_class_name"
android:layout_marginTop="20dp"
android:layout_marginLeft="5dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#FFFFFF"/>
<EditText
android:id="#+id/register_class_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/register_class_textview"
android:layout_alignBaseline="#+id/register_class_textview"
android:inputType="text"
android:hint="#string/example_name"
android:singleLine="true" >
</EditText>
<!-- Assignment Type and Grade Weight -->
<TextView
android:id="#+id/register_assign_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/register_class_textview"
android:layout_alignLeft="#+id/register_class_textview"
android:text="#string/write_assignment_type"
android:layout_marginTop="10dp"
android:textAppearance="?android:attr/textAppearanceMedium"/>
<EditText

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/register_assign_textview"
android:layout_alignLeft="#+id/register_assign_textview"
android:gravity="center_horizontal"
android:hint="#string/example_assign"
android:singleLine="true">
</EditText>
<!-- Save Button -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:gravity="bottom" >
<Button
android:id="#+id/button_save"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/save_class" />
</RelativeLayout>
<Button
android:id="#+id/btnAddNewItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/register_assign_edit"
android:layout_centerHorizontal="true"
android:layout_marginTop="22dp"
android:gravity="center_horizontal"
android:onClick="onAddNewClicked"
android:paddingLeft="5dp"
android:text="#string/more_assign"
android:textColor="#FFFFFF" />
<EditText
android:id="#+id/register_weight_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/btnAddNewItem"
android:layout_alignLeft="#+id/register_weight_textview"
android:ems="10"
android:hint="#string/example_weight"
android:inputType="number"
android:singleLine="true" >
</EditText>
<TextView
android:id="#+id/register_weight_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/register_assign_textview"
android:layout_alignBottom="#+id/register_assign_textview"
android:layout_alignParentRight="true"
android:text="#string/write_assign_percent"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
This is how the layout for the code above looks like and I want to be able to press the "Add More" Button and it inflates to "create a new row", per say, of the TextViews of Assignment Type and Grade Weight and EditTexts of the respective TextViews. But when I run the app and press add more, the new set of TextView + EditText pop up right on top of what I have rather than underneath. The following is my other xml file new_class
<?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="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/register_assign_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assignment_type"
android:textAppearance="?android:attr/textAppearanceMedium"/>
<TextView
android:id="#+id/register_weight_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assign_percent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_marginLeft="30dp"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="#+id/register_assign_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:hint="#string/example_assign"
android:singleLine="true">
</EditText>
<EditText
android:id="#+id/register_weight_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="#string/example_weight"
android:layout_marginLeft="30dp"
android:gravity="center_horizontal"
android:inputType="number"
android:singleLine="true">
</EditText>
</LinearLayout>
</LinearLayout>
And this is the Java Code that I have
public class NewClass extends Activity{
private RelativeLayout mContainerView;
private Button mAddButton;
private View mExclusiveEmptyView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_class_container);
mContainerView = (RelativeLayout) findViewById(R.id.parentView);
mAddButton = (Button) findViewById(R.id.btnAddNewItem);
}
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
//TODO: Handle Screen Rotation
}
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// TODO: Handle screen rotation:
// restore the saved items and inflate each one with inflateEditRow;
}
// onClick handler for the "Add new" button;
public void onAddNewClicked(View v) {
// Inflate a new row and hide the button self.
inflateEditRow(null);
v.setVisibility(View.GONE);
}
// onClick handler for the "X" button of each row
public void onDeleteClicked(View v) {
// remove the row by calling the getParent on button
mContainerView.removeView((View) v.getParent());
}
private void inflateEditRow(String name) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.new_class, null);
//final ImageButton deleteButton = (ImageButton) rowView
// .findViewById(R.id.buttonDelete);
final EditText editText = (EditText) rowView
.findViewById(R.id.register_assign_edit);
if (name != null && !name.isEmpty()) {
editText.setText(name);
} else {
mExclusiveEmptyView = rowView;
//deleteButton.setVisibility(View.INVISIBLE);
}
// A TextWatcher to control the visibility of the "Add new" button and
// handle the exclusive empty view.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
if (s.toString().isEmpty()) {
mAddButton.setVisibility(View.GONE);
//deleteButton.setVisibility(View.INVISIBLE);
if (mExclusiveEmptyView != null
&& mExclusiveEmptyView != rowView) {
mContainerView.removeView(mExclusiveEmptyView);
}
mExclusiveEmptyView = rowView;
} else {
if (mExclusiveEmptyView == rowView) {
mExclusiveEmptyView = null;
}
mAddButton.setVisibility(View.VISIBLE);
// deleteButton.setVisibility(View.VISIBLE);
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
});
// Inflate at the end of all rows but before the "Add new" button
mContainerView.addView(rowView, mContainerView.getChildCount() - 1);
}
}
What can I do to prevent it from overlapping and showing up underneath? And how will I be able to move the button each time it's 'updated'? Because if I move the button to the new_class xml file then it won't show up originally for me to add more views.
I tried implementing the following code and what it did was enabled me to properly get a dynamic view added the first time but each time after it was overlapping the added view.
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, R.id.register_assign_edit);
rowView.setLayoutParams(p);

This will work with having two layout files: main_layout and layout_to_include.

To use these layouts in your code:
....
setContentView(R.layout.main_layout);
....
llAddingContainer = (LinearLayout) findViewById(R.id.llAddingContainer);
// Clicking on this button will add another view from 'layout_to_include' to the ScrollView
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
View view = getLayoutInflater().inflate(R.layout.layout_to_include, null);
// Find the elements in this view and set them up
EditText et1 = (EditText) view.findViewById(R.id.editText1)
....
....
....
// Add the view to the LinearLayout inside ScrollView
llAddingContainer.addView(view);
});

I'm not sure, but you can try follow code to move any view. I recommend to use RelativeLayout like your main layout.
RelativeLayout.LayoutParams bParams1 = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
bParams1.leftMargin = (int) leftMrgn;
bParams1.topMargin = (int) topMgrn;
bParams1.height = (int) bHeight;
bParams1.width = (int) bWidth;
anyView.setLayoutParams(bParams1);

RelativeLayouts act like a FrameLayout if you don't give them any LayoutParams (constraints like below, above, center, etc.).
You can either construct the appropriate RelativeLayout.LayoutParams, or better yet, create an empty vertical LinearLayout in your first layout that will contain the rows. Then, just add the rows to the LinearLayout instead of the RelativeLayout.
