Lottie Animation not working with setExitSharedElementCallback android

I am working on Android with a Lottie animation. I implemented a shared transition on Lottie from one activity to another activity. But this is not Working. What am I doing wrong in my setExitSharedElementCallback method?

lottieAnimationView = findViewById(R.id.animation_logo);
setExitSharedElementCallback(new SharedElementCallback() {
#Override
public Parcelable onCaptureSharedElementSnapshot(View sharedElement, Matrix viewToGlobalMatrix, RectF screenBounds) {
int bitmapWidth = Math.round(screenBounds.width());
int bitmapHeight = Math.round(screenBounds.height());
Bitmap bitmap = null;
if (bitmapWidth > 0 && bitmapHeight > 0) {
Matrix matrix = new Matrix();
matrix.set(viewToGlobalMatrix);
matrix.postTranslate(-screenBounds.left, -screenBounds.top);
bitmap = Bitmap.createBitmap(bitmapWidth, bitmapHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.concat(matrix);
sharedElement.draw(canvas);
}
return bitmap;
}
});
findViewById(R.id.start_animation).setOnClickListener(new View.OnClickListener() {

How can I add drawerLayout and not to damage existed LinerLayout style?

I began doing a project without DrawableLayout. I am using mostly LinearLayout. I want to add drawer navigation android, and as I know, I need DrawableLayout.
How can I add this, and not damage everything I have now?

Well don't be afraid. It's not so difficult. Just follow the following steps to get it:-
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_green_dark">
<!-- put you linear layout here --!>
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigation_menu"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"
android:id="#+id/nv">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
Navigation Header:
<?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="wrap_content"
android:gravity="center"
android:background="#color/colorPrimaryDark">
<ImageView
android:layout_width="180dp"
android:layout_height="130dp"
android:layout_marginBottom="15dp"
android:layout_marginTop="15dp"
android:background="#drawable/ic_android_black_24dp"/>
</LinearLayout>
**Create a menu for the navigation drawer**
Right-click the res folder →Select new →Android resource file →Choose ‘menu’ under the resource type drop-down list.
Name the file as ‘navigation_menu.xml’ and copy-paste the following code into the file.
`<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/account"
android:icon="#drawable/ic_portrait_black_24dp"
android:title="My Account"/>
<item android:id="#+id/settings"
android:icon="#drawable/ic_brightness_high_black_24dp"
android:title="Settings"/>
<item android:id="#+id/mycart"
android:icon="#drawable/ic_local_grocery_store_black_24dp"
android:title="My Cart"/>
</menu>
** Lastly, in you activity:** <br>
In this last and final step, we will write Java code in the MainActivity.java file.
import android.support.annotation.NonNull;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
private DrawerLayout dl;
private ActionBarDrawerToggle t;
private NavigationView nv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dl = (DrawerLayout)findViewById(R.id.activity_main);
t = new ActionBarDrawerToggle(this, dl,R.string.Open, R.string.Close);
dl.addDrawerListener(t);
t.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
nv = (NavigationView)findViewById(R.id.nv);
nv.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
switch(id)
{
case R.id.account:
Toast.makeText(MainActivity.this, "My Account",Toast.LENGTH_SHORT).show();break;
case R.id.settings:
Toast.makeText(MainActivity.this, "Settings",Toast.LENGTH_SHORT).show();break;
case R.id.mycart:
Toast.makeText(MainActivity.this, "My Cart",Toast.LENGTH_SHORT).show();break;
default:
return true;
}
return true;
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(t.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
}`

I want to hide and unhide text using a button in android ; The code is correct but it still doesn't work

Here is the xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_hide"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.andrew.hide.Hide">
<TextView
android:text="This is the text"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="81dp"
android:id="#+id/textView"
android:textSize="40sp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<Button
android:text="Hide"
android:layout_width="match_parent"
android:layout_height="50dp"
android:id="#+id/button"
android:textSize="28sp"
android:onClick="hide"
android:layout_marginBottom="184dp" />
</RelativeLayout>
Here is the java file
package com.example.andrew.hide;
import android.app.Activity;
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.TextView;
public class Hide extends Activity {
Button b1;
TextView t1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hide);
b1=(Button) findViewById(R.id.button);
t1=(TextView) findViewById(R.id.textView);
String text=b1.getText().toString();
}
public void hide(View view) {
if (b1.getText().toString() == "Hide") {
t1.setVisibility(View.INVISIBLE);
b1.setText("Unhide");
}
if (b1.getText().toString() == "Unhide") {
t1.setVisibility(View.VISIBLE);
b1.setText("Hide");
}
}
}
I am new to android development , so ignore if this doubt is silly.
I manually checked by using Log and I found that getText works perfectly
Nothing happens whenever i click the button (b1 here),How do I fix this?

Use equals to compare strings.
Try this,
public void hide(View view) {
String text = b1.getText().toString();
if (text.equals("Hide")) {
t1.setVisibility(View.INVISIBLE);
b1.setText("Unhide");
} else if (text.equals("Unhide")) {
t1.setVisibility(View.VISIBLE);
b1.setText("Hide");
}
}

Why don't you simply check the TextView visibility and perform your actions based on that ? It's all the setters and getters right ?
b1.onClickListener(new OnClickListener() {
if (t1.getVisibility() == View.Visible) {
t1.setVisibilty(View.GONE);
//--- your code
} else {
t1.setVisibilty(View.VISIBLE);
//--- your code
}
);

How to implement image with text in Menu options in android

i am trying so hard to implement customized menu option with both image and text in menu item list but i did not get it...so please help me how to implement it...thank you in advance
here is my menu.xml
<menu 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"
tools:context="com.example.admin.sst.Signuplogin">
<item android:id="#+id/one" android:title="one"
app:showAsAction="never"
/>
<item android:id="#+id/two" android:title="two"
android:orderInCategory="100" app:showAsAction="never" />
<item android:id="#+id/three" android:title="three"
android:orderInCategory="100" app:showAsAction="never" />
</menu>

You can use PopupMenu on any view clicked.

any help would be appreciable. :)

I would recommend you to use Picasso or Glide for it. This libs not only allowed you to async load images, but you could also set up the transformations(here is ready to use circle transformations Picasso, Glide) for any image that should be loaded.
