Toasts in Android

• A toast provides simple feedback about an operation in a small popup.
• A toast is a view containing a quick little message for the user
• It only fills the amount of space required for the message and the current activity remains visible and interactive.

Creating a Toast

• First, instantiate a Toast object with one of the makeText() methods
• This method takes three parameters: Context, text message, duration for the toast.

Toast.makeText(context, text, duration).show();
Example
Toast.makeText(getApplicationContext(),"Hello Toast",Toast.SHORT_LENGTH).show();

Simple code snippet for creating a toast

layout.xml
<LinearLayout
    android:orientation="vertical"
 tools:context="com.customizationtoastapp.CustomizationToastActivity">
    <Button
        android:id="@+id/bt_customizationToast"
       android:text="Toast Customization"/>
</LinearLayout>
Activity.xml
public class CustomizationToastActivity extends AppCompatActivity implements View.OnClickListener {
    private Button btCustomizationToast;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_customization_toast);
        setUpViews();
    }
    private void setUpViews() {
        btCustomizationToast = (Button) findViewById(R.id.bt_customizationToast);

        btCustomizationToast.setOnClickListener(this);
    }
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.bt_customizationToast:
                Toast toast= Toast.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT);
                toast.show();
                break;
        }
    }

####OUTPUT

Positioning your Toast

• A standard toast notification appears near the bottom of the screen, centered horizontally.
• You can change this position with the setGravity(int, int, int) method.

Use same layout we defined previously

Activity.java
public class CustomizationToastActivity extends AppCompatActivity implements View.OnClickListener {
    private Button btCustomizationToast;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_customization_toast);
        setUpViews();
    }
    private void setUpViews() {
        btCustomizationToast = (Button) findViewById(R.id.bt_customizationToast);
        btCustomizationToast.setOnClickListener(this);
       
    }
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.bt_customizationToast:
                Toast toast= 	Toast.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT);
                toast.setGravity(Gravity.START|Gravity.AXIS_CLIP, 0, 500);
                toast.show();
                break;
            
        }
    }
}

###OUTPUT

Creating a Custom Toast View

• Create a separate layout file for custom toast view
• Use LayoutInflater for initializing the layout
• set layout to Toast with the method setView(View)

layout_custom_toast.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
    >
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="CustomToast"
    android:textSize="30sp"
    />
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_account_circle_black_24dp"
        />
</LinearLayout>
actvity_layout.xml
<LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:orientation="vertical"    
android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.customizationtoastapp.CustomizationToastActivity">
    <Button
        android:id="@+id/bt_customizationToast_layout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Toast Customization layout"/>
</LinearLayout>
Activity.xml
public class CustomizationToastActivity extends AppCompatActivity implements View.OnClickListener {

    private Button btCustomizationToastLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_customization_toast);
        setUpViews();
    }
    private void setUpViews() {
        btCustomizationToastLayout = (Button) findViewById(R.id.bt_customizationToast_layout);
        btCustomizationToastLayout.setOnClickListener(this);
    }
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            
            case R.id.bt_customizationToast_layout:
                setToastLayoutout();
                break;
        }
    }
    private void setToastLayoutout() {
        LayoutInflater layoutInflater = getLayoutInflater();
        View toastLayout = layoutInflater.inflate(R.layout.layout_toast, null);
        Toast toast = new Toast(getApplicationContext());
        toast.setView(toastLayout);
        toast.show();
    }
}
