I am trying to change the background of message item in a chat app but instead of changing the background of the message item it changes everything around the message on its line. I have tried other solutions to this problem but they all end up like below.
Example:
Here is the code for the spawning of the item:
mUserMsg = new FirebaseRecyclerAdapter<ChatMessage, ViewHolder>(ChatMessage.class,R.layout.chat_item_sent,ViewHolder.class,mRef)
{
#Override
protected void populateViewHolder(ViewHolder view, ChatMessage message, int position) {
LinearLayout messageLine = view.layout;
TextView messgaeText = view.message;
TextView senderText = view.sender;
ImageView leftPic = view.leftPic;
View mView= view.fucker;
if (message.getUserID().equals(USER_ID))
{
messageLine.setGravity(Gravity.END);
leftPic.setVisibility(View.GONE);
messageLine.setBackground(ContextCompat.getDrawable(mView.getContext(),R.drawable.round_corners_sent));
messgaeText.setText(message.getMessageText());
senderText.setText(message.getUserID());
}
else
{
messageLine.setGravity(Gravity.LEFT);
Picasso.with(getApplicationContext()).load(Uri.parse(picURL)).fit().centerCrop().into(leftPic);
messgaeText.setText(message.getMessageText());
senderText.setText(message.getUserID());
}
}
};
recyclerView.setLayoutManager(mLinearLayoutManager);
recyclerView.setAdapter(mUserMsg);
}
This is the drawable I am trying to change to:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="5dp"/>
<stroke
android:width="40dp"
android:color="#a8bbcf"/>
<solid android:color="#a8bbcf"/>
</shape>
Here is the chat item layout:
<?xml version="1.0" encoding="utf-8"?>

This is file xml of bottom sheet dialog fragment. I want to set fixed height for fragment when it showed in other fragment. Because in bottom sheet I have recycler view so when I scroll bottom sheet expanded to full screen. I don't want that. I want to set fixed height for it. And I want to button Apply always display at the bottom when I scrool.
To full height:
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val dialog = context?.let { BottomSheetDialog(it, theme) }
dialog?.setOnShowListener {
val bottomSheetDialog = it as BottomSheetDialog
val parentLayout =
bottomSheetDialog.findViewById<View>(com.google.android.material.R.id.design_bottom_sheet)
parentLayout?.let { bottomSheet ->
val behaviour = BottomSheetBehavior.from(bottomSheet)
setupFullHeight(bottomSheet)
behaviour.state = BottomSheetBehavior.STATE_EXPANDED
}
}
return dialog ?: super.onCreateDialog(savedInstanceState)
}
private fun setupFullHeight(bottomSheet: View) {
val layoutParams = bottomSheet.layoutParams
layoutParams.height = WindowManager.LayoutParams.MATCH_PARENT
bottomSheet.layoutParams = layoutParams
}
button Apply, You can set top of view, or stick to bottom use RelativeLayout
Add Layout custom fix height
android:layout_height="500dp"
Add Layout peek height
app:behavior_peekHeight="100dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
I have listview for my chat page....whenever i type new message in listview it not automatically scrolled down at botton.

When I add new text in listview then it should go to bottom of the page to see new messsage
You can try this out. But i suggest you to use to recyclerview instead of listview for Chat module.
private void scrollToBottom() {
listView.post(new Runnable() {
#Override
public void run() {
listView.setSelection(adapter.getCount() - 1);
}
});
}
I build my own custom Dialogbut its not opening when i am clicking on ImageView. I also checked by putting break point Dialog is coming null how to rectify it. I want to shift TextView of id unread_count to the right of parent . How can I do this ?
If I set android:layout_alignParentRight="true" then I have the following picture :
<?xml version="1.0" encoding="utf-8"?>

Java code
private ImageView dialogBox;
Dialog customDialog;
customDialog = new Dialog(getActivity());
dialogBox = (ImageView) view.findViewById(R.id.dialogBox);
dialogBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showDialog();
}
});
private void showDialog() {
customDialog.setContentView(R.layout.dialog_info);
}
You can try this way, you have to find dialog views using dialog.findViewById
Dialog dialog = new Dialog(mActivity);
dialog.setContentView(R.layout.dialog_info);
//dialog.setCancelable(false); //set Cancelable
ImageView dialogBox = (ImageView) dialog.findViewById(R.id.imgViewID);
dialogBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
//for big size dialog
/* Window window = dialog.getWindow();
window.setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);*/
I check you dialog_info.xml code
You need to improve your design code, you don't need to take static height and weight
I update your layout code here

You forgot to call show method on the custom dialog. Change your code to
private void showDialog() {
customDialog.setContentView(R.layout.dialog_info);
// Add this line
customDialog.show();
}

My JAVA codes:
public class UpdateActivity extends BaseActivity {
#BindView(R.id.dialogEndCount_buttonsLay)
LinearLayout dialogEndCount_buttonsLay;
private Window window;
private Activity activity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_update);
//Initialize
ButterKnife.bind(this);
activity = this;
window = activity.getWindow();
//Set color to statusBar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.setStatusBarColor(getResources().getColor(R.color.tabHomeColor));
}
//Set dynamically weight
dialogEndCount_buttonsLay.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
How can I fix this problem?
If you want set dynamically weightSum just use this code :
dialogEndCount_buttonsLay.setWeightSum(3f);
i hope help you
You're mixing LinearLayout and RelativeLayout. Change your layout to use a LinearLayout then weight is an available property on your LayoutParams.
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
params.weight = 1f
I can make the dynamic UI without problems, but I don't know how to access the view with findviewbyid (R.id._____) I don't know what to put in the blank.
.java code
public class newList extends AppCompatActivity {
Button btnAddItem;
RelativeLayout layout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_list);
// allows the creation of dynamic rows
btnAddItem = (Button) findViewById(R.id.addItem);
btnAddItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater inflater = getLayoutInflater();
ViewGroup parent = (ViewGroup) findViewById(R.id.linearVert);
inflater.inflate(R.layout.rows, parent);
}
});
}

There will be no unique R.id value at the activity level. For example, suppose the user taps the button 10 times, so you inflate the R.layout.rows layout 10 times. As a result, there will be 10 R.id.linearHor widgets, 10 R.id.itemPrice widgets, and so on.
Always call findViewById() on something that is guaranteed to give you a unique result. In this case — as with ListView, GridView, RecyclerView, etc. — you need to use other approaches to find the correct row View, then call findViewById() on that View to get at its child widgets.
