In Android, Is it possible to make Text Tag separation in editext Like Stack overflow (see the image)?

I want to create this kind of separation between commas(,)? like StackOverflow Tags

Try this:
In MainActivity.java
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.SwitchCompat;
import android.widget.CompoundButton;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.List;
import me.originqiu.library.EditTag;
public class MainActivity extends AppCompatActivity
implements SwitchCompat.OnCheckedChangeListener {
private EditTag editTagView;
private SwitchCompat statusSwitchView;
private List<String> tagStrings = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editTagView = (EditTag) findViewById(R.id.edit_tag_view);
statusSwitchView = (SwitchCompat) findViewById(R.id.status_switch);
statusSwitchView.setOnCheckedChangeListener(this);
for (int i = 0; i < 10; i++) {
tagStrings.add("test" + i);
}
//Set tag add callback before set tag list
editTagView.setTagAddCallBack(new EditTag.TagAddCallback() {
#Override
public boolean onTagAdd(String tagValue) {
if ("test1".equals(tagValue)) {
return false;
} else {
return true;
}
}
});
editTagView.setTagDeletedCallback(new EditTag.TagDeletedCallback() {
#Override
public void onTagDelete(String deletedTagValue) {
Toast.makeText(MainActivity.this, deletedTagValue, Toast.LENGTH_SHORT).show();
}
});
editTagView.setTagList(tagStrings);
editTagView.addTag("hello world!");
editTagView.removeTag("test3");
}
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
editTagView.setEditable(isChecked);
}
}

Generating QR Code on different activity in android

i have been trying to create a QR Code generator that generates the QR Code on a separate activity on button click. Below is my code but it crushes on button click. Where did i go wrong?
First class is MainActivity.class:
package com.example.profmox.myapplication;
import android.content.Intent;
import android.graphics.Bitmap;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.TextView;
import com.google.zxing.BarcodeFormat;
import com.google.zxing.MultiFormatWriter;
import com.google.zxing.WriterException;
import com.google.zxing.common.BitMatrix;
import com.journeyapps.barcodescanner.BarcodeEncoder;
public class MainActivity extends AppCompatActivity {
TextView tx1;
Button btn1, btn2;
EditText edt1,edt2;
CheckBox ch;
String text2qr;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edt1 = (EditText)findViewById(R.id.edit1);
edt2 = (EditText)findViewById(R.id.edit2);
btn1 = (Button)findViewById(R.id.login);
btn2 = (Button)findViewById(R.id.signup);
ch = (CheckBox)findViewById(R.id.check);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.v("EditText", edt1.getText().toString());
Log.v("EditText", edt2.getText().toString());
// text2qr = edt1.getText().toString().trim();
// MultiFormatWriter mfw = new MultiFormatWriter();
// try{
// BitMatrix btm = mfw.encode(text2qr, BarcodeFormat.QR_CODE,250,250);
// BarcodeEncoder ben = new BarcodeEncoder();
// Bitmap bmap = ben.createBitmap(btm);
// UserScreen.qr.setImageBitmap(bmap);
// }catch (WriterException e){
// e.printStackTrace();
// }
startActivity(new Intent(MainActivity.this, UserScreen.class));
}
});
btn2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, SignUp.class));
}
});
}
}
The layout file for the MainActivity class:

Implementing formulas into each value in the spinner which will change the result everytime the user change selected value

I am creating a diet app for myself and I do not know how to transfer result from one calculation which was done in a different activity and use it in another one.
To make things more complicated, I want my spinner in MoreLooseWeightDetails.class to have a list of different diet types which have different fat, proteins and carb ratio. Every time the user choose different type it should automatically change the ratio.
This is where the calculation is being done and has to be trnasfered to MoreLooseWeightDetails.class
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;
public class LooseWeight extends AppCompatActivity {
TextView TotalCal;
EditText numb2;
Spinner ActLvl;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_loose_weight);
numb2 = (EditText) findViewById(R.id.value1);
ActLvl = (Spinner) findViewById(R.id.value2);
TotalCal = (TextView)findViewById(R.id.resultDisplay);
final Spinner ActLvl = (Spinner)findViewById(R.id.value2);
ArrayAdapter<String> myAdapter = new ArrayAdapter<>(LooseWeight.this, android.R.layout.simple_expandable_list_item_1,getResources().getStringArray(R.array.lvl));
myAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
ActLvl.setAdapter(myAdapter);
Button calcBtn = (Button)findViewById(R.id.result);
calcBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick (View view) {
float numb3 = Float.parseFloat(numb2.getText().toString());
float a = numb3 * 24;
float b = a * Float.parseFloat(ActLvl.getSelectedItem().toString());
float c = b - 500;
TotalCal.setText(Float.toString(c));
}
});
Button extra = (Button)findViewById(R.id.advance);
extra.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(),MoreLooseWeightDetails.class);
startActivity(intent);
}
});
}
}
Here is the MoreLooseWeightDetails.class

How to include GridView and ListView together in one layout

I am building an app where i have to use both gridview and listview in same activity but the problem is gridview items are clickable but not the listview this is my xml of activity...

please help me how to make listview item and row clickable ......

Have you tried android:clickable="true"?
like:
<TableRow
android:id="#+id/tableRow1"
android:clickable="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="23dp" >

You need to determine the height of the grid view first. Use this tutorial.
http://www.devexchanges.info/2015/03/combining-gridview-and-listview-in-one.html

Firstly, you only need to put 2 RecyclerViews object to your activity/fragment layout. For better scroll later, please wrap theme in a NestedScrollView like this:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:background="#ffffe0"
tools:context="info.devexchanges.gridlistrecyclerview.MainActivity">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:text="#string/os"
android:textStyle="bold" />
<android.support.v7.widget.RecyclerView
android:id="#+id/grid"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:text="#string/corporation"
android:textStyle="bold" />
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
Of course, you always need to creating layout for each RecyclerView item. In this every item is a CardView:
item_list.xml
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/image"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_marginLeft="5dp"
android:contentDescription="#string/app_name" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_toRightOf="#+id/image"
android:gravity="center" />
</RelativeLayout>
</android.support.v7.widget.CardView>
item_grid.xml
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
app:cardCornerRadius="10dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
<ImageView
android:id="#+id/image"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:contentDescription="#null" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/image"
android:layout_marginTop="5dp"
android:background="#color/colorPrimaryDark"
android:gravity="center"
android:padding="5dp"
android:textColor="#ffffff"
android:textStyle="bold" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Now, we must create 2 adapter classes for 2 RecyclerViews based on RecyclerView.Adapter:
ListViewAdapter.java
import android.app.Activity;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.List;
import info.devexchanges.gridlistrecyclerview.R;
import info.devexchanges.gridlistrecyclerview.RecyclerViewItem;
public class ListViewAdapter extends RecyclerView.Adapter<ListViewAdapter.ViewHolder> {
private Activity activity;
private List<RecyclerViewItem> items;
public ListViewAdapter(Activity activity, List<RecyclerViewItem> items) {
this.activity = activity;
this.items = items;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = activity.getLayoutInflater();
View view = inflater.inflate(R.layout.item_list, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, final int position) {
viewHolder.imageView.setImageResource(items.get(position).getDrawableId());
viewHolder.textView.setText(items.get(position).getName());
}
#Override
public int getItemCount() {
return items.size();
}
/**
* View holder to display each RecylerView item
*/
protected class ViewHolder extends RecyclerView.ViewHolder {
private ImageView imageView;
private TextView textView;
public ViewHolder(View view) {
super(view);
imageView = (ImageView) view.findViewById(R.id.image);
textView = (TextView)view.findViewById(R.id.text);
}
}
}
GridViewAdapter.java
import android.app.Activity;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.List;
import info.devexchanges.gridlistrecyclerview.R;
import info.devexchanges.gridlistrecyclerview.RecyclerViewItem;
public class GridViewAdapter extends RecyclerView.Adapter<GridViewAdapter.ViewHolder> {
private List<RecyclerViewItem> items;
private Activity activity;
public GridViewAdapter(Activity activity, List<RecyclerViewItem> items) {
this.activity = activity;
this.items = items;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
LayoutInflater inflater = activity.getLayoutInflater();
View view = inflater.inflate(R.layout.item_grid, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(GridViewAdapter.ViewHolder viewHolder, int position) {
viewHolder.imageView.setImageResource(items.get(position).getDrawableId());
viewHolder.textView.setText(items.get(position).getName());
}
#Override
public int getItemCount() {
return items.size();
}
/**
* View holder to display each RecylerView item
*/
protected class ViewHolder extends RecyclerView.ViewHolder {
private ImageView imageView;
private TextView textView;
public ViewHolder(View view) {
super(view);
textView = (TextView)view.findViewById(R.id.text);
imageView = (ImageView) view.findViewById(R.id.image);
}
}
}
There is no special point in your activity or fragment programmatically code, locating all xml elements from layout file, create LayoutManager for RecyclerViews, initializing adapters and attaching them,...This is full code for my main activity:
MainActivity.java
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import java.util.ArrayList;
import info.devexchanges.gridlistrecyclerview.adapter.GridViewAdapter;
import info.devexchanges.gridlistrecyclerview.adapter.ListViewAdapter;
public class MainActivity extends AppCompatActivity {
private RecyclerView listView;
private RecyclerView gridView;
private ListViewAdapter listViewAdapter;
private GridViewAdapter gridViewAdapter;
private ArrayList<RecyclerViewItem> corporations;
private ArrayList<RecyclerViewItem> operatingSystems;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (RecyclerView) findViewById(R.id.list);
gridView = (RecyclerView) findViewById(R.id.grid);
setDummyData();
listView.setHasFixedSize(true);
gridView.setHasFixedSize(true);
//set layout manager and adapter for "ListView"
LinearLayoutManager horizontalManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
listView.setLayoutManager(horizontalManager);
listViewAdapter = new ListViewAdapter(this, corporations);
listView.setAdapter(listViewAdapter);
//set layout manager and adapter for "GridView"
GridLayoutManager layoutManager = new GridLayoutManager(this, 2);
gridView.setLayoutManager(layoutManager);
gridViewAdapter = new GridViewAdapter(this, operatingSystems);
gridView.setAdapter(gridViewAdapter);
}
private void setDummyData() {
corporations = new ArrayList<>();
corporations.add(new RecyclerViewItem(R.drawable.microsoft, "Microsoft"));
corporations.add(new RecyclerViewItem(R.drawable.apple, "Apple"));
corporations.add(new RecyclerViewItem(R.drawable.google, "Google"));
corporations.add(new RecyclerViewItem(R.drawable.oracle, "Oracle"));
corporations.add(new RecyclerViewItem(R.drawable.yahoo, "Yahoo"));
corporations.add(new RecyclerViewItem(R.drawable.mozilla, "Mozilla"));
operatingSystems = new ArrayList<>();
operatingSystems.add(new RecyclerViewItem(R.drawable.bbos, "BlackBerry OS"));
operatingSystems.add(new RecyclerViewItem(R.drawable.ios, "iOS"));
operatingSystems.add(new RecyclerViewItem(R.drawable.tizen, "Tizen"));
operatingSystems.add(new RecyclerViewItem(R.drawable.android, "Android"));
operatingSystems.add(new RecyclerViewItem(R.drawable.symbian, "Symbian"));
operatingSystems.add(new RecyclerViewItem(R.drawable.firefox_os, "Firefox OS"));
operatingSystems.add(new RecyclerViewItem(R.drawable.wp_os, "Windows Phone OS"));
}
}
And this is the POJO class of this project:
RecyclerViewItem.java
public class RecyclerViewItem {
private int drawableId;
private String name;
public RecyclerViewItem(int drawableId, String name) {
this.drawableId = drawableId;
this.name = name;
}
public int getDrawableId() {
return drawableId;
}
public String getName() {
return name;
}
}
NOTE: Never forget to put RecyclerView and CardView dependencies to your app-level build.gradle file:
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
