Issue when using Scrollview inside Dialog

Issue when using Scrollview inside Dialog - android

I am inflating a layout inside a dialog, which consist of a scrollview but the layout is not scrolling. I have referred so many questions from stackoverflow but then also its not working. My layout.xml is given below:
<?xml version="1.0" encoding="utf-8"?>

android:layout_marginTop="10dp"
android:scaleType="fitXY"
android:src="#drawable/line_y_h" />
</LinearLayout>
</ScrollView>
Dialog code
public void show_Alert_version_custom(String str, final String url,
final String exitStatus)// use for
{
final Dialog dialog = new Dialog(Splash.this);
dialog.setContentView(R.layout.version_update);
dialog.setTitle(getString(R.string.alert_title));
Button dialogButton2 = (Button) dialog.findViewById(R.id.btn_remind);
dialogButton = (Button) dialog.findViewById(R.id.btn_upgrade);
ImageView viewLine = (ImageView) dialog.findViewById(R.id.imageView2);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {}
});
// if button is clicked, close the custom dialog
dialogButton2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {}
});
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">
</LinearLayout>
</ScrollView>

Simple, 1st need to create an newcustom_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:cardCornerRadius="8dp"
app:cardElevation="15dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="14dp"
android:gravity="center"
android:text="Quit Earning?"
android:textColor="#android:color/black"

android:layout_marginEnd="20dp"

android:text="You are 400pts. away from \n unlocking rewards. quit Earning?"
android:textSize="18dp"
android:textStyle="bold" />
</android.support.v7.widget.CardView>
</LinearLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/frmNo"
android:layout_marginRight="45dp"
android:layout_marginTop="75dp">
<android.support.design.widget.FloatingActionButton
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#android:color/transparent"
app:backgroundTint="#color/fab2" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:elevation="6dp"
android:text="No"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#android:color/white"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/frmOk"
android:layout_marginLeft="50dp"
android:layout_marginTop="75dp">

android:elevation="6dp"
android:text="Ok"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#android:color/white"
android:textStyle="bold" />
</FrameLayout>
</FrameLayout>
Then, in java file (in activity) paste this code
public class ViewDialog {
public void showDialog(Activity activity) {
final Dialog dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.newcustom_layout);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
FrameLayout mDialogNo = dialog.findViewById(R.id.frmNo);
mDialogNo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
FrameLayout mDialogOk = dialog.findViewById(R.id.frmOk);
mDialogOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
dialog.cancel();
}
});
dialog.show();
}
}
Finally you can call it wherever you want.
ViewDialog alert = new ViewDialog();
alert.showDialog(CustomDialogActivity.this);

Inside your dailog.xml

You can change your button by using
android:src=#drawable/image
You have to extends Dialog and implements OnClickListener
public class CustomDialogClass extends Dialog implements
android.view.View.OnClickListener {
public Activity c;
public Dialog d;
public Button yes, no;
public CustomDialogClass(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_dialog);
yes = (Button) findViewById(R.id.btn_yes);
no = (Button) findViewById(R.id.btn_no);
yes.setOnClickListener(this);
no.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_yes:
c.finish();
break;
case R.id.btn_no:
dismiss();
break;
default:
break;
}
dismiss();
}
}
Call Dialog
CustomDialogClass cdd=new CustomDialogClass(Activity.this);
cdd.show();

Maybe try this method

Have you considered adding a headerview to listview. You could actually use a layout as header for listview. This way, you views on header will never overflow on to listview.
final ListView lstVRHDetails = (ListView) getActivity().findViewById(R.id.listview);
LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View headerView = inflater.inflate(<header layout>, new LinearLayout(getActivity()), false);
headerView.findViewById(R.id.rlFromDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.rlToDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.imgUpdate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
headerView.setLayoutParams(new ListView.LayoutParams(ListView.LayoutParams.MATCH_PARENT, ListView.LayoutParams.WRAP_CONTENT));
lstVRHDetails.addHeaderView(headerView);

In xml of row_layout I've set a delete button as follows

here is onClickDelete method
public void onClickDelete(View v)
{
ListView lvItems = getListView();
//get the row the clicked button is in
LinearLayout vwParentRow = (LinearLayout)v.getParent();
TextView child = (TextView) vwParentRow.getChildAt(0);
child.setText("Delete Clicked");
}
When i press delete, it shows invocationtargetexception at (TextView child = (TextView) vwParentRow.getChildAt(0);)
Sorry if this is very basic mistake. I am new to android.
Thank you for your reply.

It's better
TextView child = (TextView)findViewById("yourtextfieldIDHere");
child.setText("Delete Clicked");

Listview click listener not responding

I have a list view and want to perform clickable event on it. I did it before. but now its not working. I have added my XML as well. I just need to move from one actvity to other on click in list view.
CustomFinalSubmit_ItemDetail item = new CustomFinalSubmit_ItemDetail(Final_Submit.this , R.layout.customview_finalsubmit_itemdetails, itemInfo);
itemList.setAdapter(item);
itemList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
FinalSubmitItem pos = itemInfo.get(position);
String itemType = pos.getItemType();
String itemCountry = pos.getItemCountry();
String itemSerial = pos.getItemNo();
pos.setChecked(true);
Intent inn = new Intent(getApplicationContext(), FinalSubmitDetails.class);
inn.putExtra("itemType", itemType);
inn.putExtra("itemCountry", itemCountry);
inn.putExtra("itemSerial", itemSerial);
startActivity(inn);
}
});
Here is my main Xml:

I did it this way:
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
your code
}});
Just add this much code to my customview

Recently I had the same problem after adding a ToggleButton to my list items. The solution for me was to add android:descendantFocusability="blocksDescendants" to the layout of the item.
Here is the whole XML:
<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="wrap_content"
android:layout_margin="5dp"
android:padding="5dp"
android:paddingLeft="15dp"
android:descendantFocusability="blocksDescendants" >
<TextView
android:id="#+id/watch_roadName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Addresse"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="bold" />
<ToggleButton
android:id="#+id/watch_button_arrived"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/watch_roadName"
android:layout_alignParentRight="true"
android:textOn="#string/arrived"
android:textOff="#string/arrived"
android:text="#string/arrived" />
</RelativeLayout>

android:descendantFocusability="blocksDescendants"

How to populate the same view with layout inflater?

I have a layout and every time my button is pressed I want to add a group of views stored in another layout. This is the way I tried it so far. The error in logcat is:
"E/AndroidRuntime(7900): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."
Code:
material_cost.xml

android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5D8" />
</LinearLayout>
</LinearLayout>
And finally my class:
public class MaterialActivity extends Activity implements OnClickListener {
Button btnAdd;
LinearLayout rootLayout;
View layoutItem;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.material_cost);
btnAdd = (Button) findViewById(R.id.btnMaterialAdd);
rootLayout = (LinearLayout) findViewById(R.id.materialWrapper);
layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, rootLayout,false);
rootLayout.addView(layoutItem);
btnAdd.setOnClickListener(this);
}
public void onClick(View v){
switch (v.getId()){
case R.id.btnMaterialAdd:{
inflateEntry();
break;
}
}
}
private void inflateEntry() {
// TODO Auto-generated method stub
Log.v("debug","pressed");
rootLayout.addView(layoutItem);
}
}

you need to inflate the view again every time you click the button:
private void inflateEntry()
{
// TODO Auto-generated method stub
Log.v("debug","pressed");
View layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, null);
rootLayout.addView(layoutItem);
}

Issue when using Scrollview inside Dialog - android

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"> </LinearLayout> </ScrollView>
