custom view with overlapping - android

I define layout row which I inflate and add view pragmatically to a linear layout.
I wanna something like this,
https://i.stack.imgur.com/EKPmJ.png
Here is xml of my main activity where I am inflating the costume view row
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.skw.customeviewdemo.MainActivity">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/inflate"
android:text="inflate"/>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/list_container">
</LinearLayout>
</LinearLayout>
here is my xml code of row which I am inflating:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="its text view"
/>
<Button
android:id="#+id/nameButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/name"
/>
<ImageView
android:layout_marginTop="-25dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
here is my java code
public class MainActivity extends AppCompatActivity {
Button b;
LinearLayout l1;
Context context;
Boolean isViewCreated = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final String Namearray[] = {"sagar", "ranjeet", "akash", "kate"};
this.context = this;
b = (Button) findViewById(R.id.inflate);
l1 = (LinearLayout) findViewById(R.id.list_container);
createViews(Namearray);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(l1.getVisibility() == View.VISIBLE && isViewCreated)
{
l1.setVisibility(View.GONE);
}
else
{
l1.setVisibility(View.VISIBLE);
}
}
});
}
void createViews(final String[] namearray)
{
for(int i=0;i < namearray.length;i++){
final int j = i;
View view = LayoutInflater.from(context).inflate(R.layout.layout_item,null);
TextView button1 = (TextView) view.findViewById(R.id.name);
Button button2 = (Button) view.findViewById(R.id.nameButton);
button1.setText("HELLO " + namearray[i]);
button2.setText("Click to know my name ");
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context,"Hello " + namearray[j],Toast.LENGTH_LONG).show();
}
});
view.setId(generateViewId());
try {
l1.addView(view);
isViewCreated = true;
}
catch (Exception e)
{
}
}
l1.setVisibility(View.GONE);
}
private static final AtomicInteger viewIdGenerator = new AtomicInteger(15000000);
public static int generateViewId() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
return generateUniqueViewId();
} else {
return View.generateViewId();
}
}
private static int generateUniqueViewId() {
while (true) {
final int result = viewIdGenerator.get();
// aapt-generated IDs have the high byte nonzero; clamp to the range under that.
int newValue = result + 1;
if (newValue > 0x00FFFFFF) newValue = 1; // Roll over to 1, not 0.
if (viewIdGenerator.compareAndSet(result, newValue)) {
return result;
}
}
}
}
but when I inflate row my image view get cutoff which I not want I tried with negative margin but it not work
here what it looks like
custom overlapping row
what I do so I over lap image to above view?


Try changing your layout to this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="its text view"
/>
<Button
android:id="#+id/nameButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/name"
/>
</RelativeLayout>
<ImageView
android:layout_marginTop="25dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
When you put in another row, that row needs to be pushed up so the android icon that is there now overlays it.

this is my question yearwise activity(from this I launched the fragment activity)

super.onCreate(savedInstanceState);
setContentView(R.layout.question_yearwise);
Button btn2018ii = (Button)findViewById(R.id.btn2018ii);

MyServerData2018ii.getInstance().setTestState("inProgress");
startActivity(Quiz2018ii);

});
}
}

Replace the method like this,
mainView.findViewById(R.id.check_results).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

You need to use the recyclerview to display your list items. Using recyclerview you can get view like -
View view = recyclerview.findViewHolderForAdapterPosition(pos).itemView;
Spinner spinner = view.findViewById(R.id.mySpinner);
This will return you a spinner of whichever position you have passed and afterwards get data from it.
Similarly, you can get view of edittext by using -
EditText edtTxt = view.findViewById(R.id.myEdtTxt);
To see how to get data from database and display that in recyclerview, check the example here - https://github.com/incipientinfo/db-queries

problems with scrollview (android-studio)

My problem is that I duplicate the contents of the layout and I do not understand the reason.
I'm working with fragments and the code is as follows
fragment code

I want it to stay the same as in the first photo, but as soon as I click on one of the edittext or move the screen is set as the second
Thank you very much

if you are adding data in layout dynamically, then you need to remove all views and add them again
Can you please show code what you are doing in Fragment class where you adding views in framlayout

Android Listview button doesn't work

I created a custom listview with the base adapter, but for some reason can not click on the button inside the individual list views.
Here is the code the the main layout:
<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" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Light List"
android:id="#+id/lightName"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/loginbutton"
android:id="#+id/button"
android:onClick="buttonClicked"
android:layout_alignParentBottom="true"
android:layout_alignLeft="#+id/lightName"
android:layout_alignStart="#+id/lightName" />
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lightList"
android:layout_below="#+id/lightName"
android:layout_above="#+id/button"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"/>
</RelativeLayout>
Here is the code for views in the list:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/lightList"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="#+id/lightName"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="#+id/statusText"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/buttonoff"
android:focusable="true"
android:enabled="true"
android:clickable="true" />
</LinearLayout>
Lastly here is the adapter code:
public ArrayList<myLight> dataSet = new ArrayList<myLight>();
public void makeLightList(ArrayList<myLight> lights) {
Iterator<myLight> iter = lights.iterator();
while(iter.hasNext()) {
dataSet.add(iter.next());
}
}
#Override
public int getCount() {
return dataSet.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View v;
LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.lightlistlayout, null);
TextView name = (TextView) findViewById(R.id.lightName);
name.setText(dataSet.get(position).name);
TextView status = (TextView) findViewById(R.id.statusText);
if(dataSet.get(position).reachable) {
if(dataSet.get(position).isOn) {
status.setText("Light is On");
} else {
status.setText("Light is Off");
}
} else {
status.setText("Light is currently not reachable");
}
dataHolder dh = new dataHolder();
dh.name = dataSet.get(position).name;
//Handle Off button click from list view
Button offButton = (Button) findViewById(R.id.buttonoff);
offButton.setTag(dh);
offButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dataHolder dhv = new dataHolder();
dhv = (dataHolder)v.getTag();
Toast.makeText(getBaseContext(), dhv.name + " Turned Off", Toast.LENGTH_LONG).show();
}
});
return v;
}
};
I am not sure if my onclicklistener is correct as I can't click on the button at all yet. Here is a picture showing the button. I have messed with different focus and clickable settings in the xml file and no luck. I added a seeker bar that I was able to slide that back and forth, but the button will not let me click it.

v = inflater.inflate(R.layout.lightlistlayout, null);
Here you have inflated the row file for your adapter and the below are your id initialization and for that you have not added your view to your id, so try this.
TextView name = (TextView) v.findViewById(R.id.lightName);
TextView status = (TextView) v.findViewById(R.id.statusText);
Button offButton = (Button) v.findViewById(R.id.buttonoff);

try changing
android:focusable="true" to android:focusable="false" in Button's xml

Adapting a layout using a Dialog Fragment

I'm trying to adapt a layout in a dialog fragment to show an imageview, a text view and two butttons, but I have problem adapting the layout in it.
I get this:
http://kitsord.com/imagestack/Screenshot_2014-05-22-11-35-22.png
And the output should look something like this:
http://kitsord.com/imagestack/looks.png
So I don't know why the text and the buttons don't show correctly.
The DialogFragment is this one:
public class LearnFragment extends DialogFragment {
ImageView imgC;
VideoView myVideoView;
View root ;
TextView textv ;
ImageButton next , atras;
Integer contador;
public static LearnFragment newInstance() {
LearnFragment f = new LearnFragment();
return f;
}
#Override

if (getDialog() != null) {
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawableResource(android.R.color.transparent);
}
LayoutInflater inflaterr = getActivity().getLayoutInflater();
root = inflaterr.inflate(R.layout.aprender_fragment_display, null);
myVideoView = (VideoView)root.findViewById(R.id.videos_aprender);
imgC =(ImageView) root.findViewById(R.id.imagenes_aprender);
textv = (TextView) root.findViewById(R.id.text_aprender);
next = (ImageButton) root.findViewById(R.id.btnnext_aprender);
atras = (ImageButton) root.findViewById(R.id.btnatras_aprender);
myVideoView.setVisibility(View.GONE);
imgC.setVisibility(View.GONE);
textv.setVisibility(-1);
if(contador == 0) {
atras.setVisibility(-1);
} else if(contador > 0 && contador < LearnAdapter.imagenesAprender.size() - 1){
next.setVisibility(0);
atras.setVisibility(0);
} else if(contador == LearnAdapter.imagenesAprender.size() - 1) {
next.setVisibility(-1);
}
startIt(GridViewFragmet.nombrearchivo);
next.setOnClickListener(new View.OnClickListener(){
public void onClick(View view){
myVideoView.setVisibility(View.GONE);
imgC.setVisibility(View.GONE);
textv.setVisibility(-1);
if(contador + 1 < LearnAdapter.imagenesAprender.size()){
++contador;
startIt(LearnAdapter.imagenesAprender.get(contador));
atras.setVisibility(0);
if(contador == LearnAdapter.imagenesAprender.size() - 1){
next.setVisibility(-1);
}
}
}
});
atras.setOnClickListener(new View.OnClickListener(){
public void onClick(View view){

imgC.setVisibility(View.GONE);
textv.setVisibility(-1);
if(contador - 1 >= 0){
--contador;

next.setVisibility(0);
if(contador == 0) {
atras.setVisibility(-1);
}
}
}
});
return root;
}
public void startIt(String archivo){
if(archivo.substring(archivo.lastIndexOf(".") + 1).equals(variablesGlobales.IMAGENES.obtenerinfo())) {
textv.setVisibility(0);
textv.setText(archivo.substring(archivo.lastIndexOf("/")+1, archivo.lastIndexOf(".")));

Bitmap bmp = BitmapFactory.decodeFile(archivo);

} else {
textv.setVisibility(0);
textv.setText(archivo.substring(archivo.lastIndexOf("/")+1, archivo.lastIndexOf(".")));
myVideoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
myVideoView.setVisibility(View.VISIBLE);
myVideoView.setZOrderOnTop(true);
myVideoView.setVideoPath(archivo);
myVideoView.start();
}
}
#SuppressWarnings("deprecation")
#Override
public void onStart() {
super.onStart();
// change dialog width
if (getDialog() != null) {
int fullWidth = getDialog().getWindow().getAttributes().width;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
Display display = getActivity().getWindowManager().getDefaultDisplay();

}
final int padding = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 24, getResources()
.getDisplayMetrics());
int w = fullWidth - padding;
int h = getDialog().getWindow().getAttributes().height;
getDialog().getWindow().setLayout(w, h);
}
}
}
The layout is this one:

I found my problem. The problem was at my class of Dialog Fragment.
The line that was giving me the error was this one:
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
That was what affected the whole dialog and moved the layout.
