Tooltips

Simple to use library for android, Enabling to add a tooltip near any view with ease

Instructions

Add a dependency to your app build.gradle

dependencies {
    implementation 'com.tomergoldst.android:tooltips:1.1.0'
}

Create a ToolTipsManager object

public class MainActivity extends Activity {
    
    ToolTipsManager mToolTipsManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        mToolTipsManager = new ToolTipsManager();
        
    }

}

Use the ToolTip.Builder to construct your tip

public class MainActivity extends Activity {
    
     @Override
     public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        
        ToolTip.Builder builder = new ToolTip.Builder(this, mTextView, mRootLayout, "Tip message", ToolTip.POSITION_ABOVE);
    }
}

mTextView here is the view which near it the tip will be shown and mRootLayout is the layout where the tip view will be added to. The root layout must be of RelativeLayout, FrameLayout or similar. LinearLayout won't work but you can always wrap your LinearLayout with another layout. Prefer to pass in a layout which is higher in the xml tree as this will give the tip view more visible space.

OPTIONAL: Customize your tip with background color, text color, alignment, text gravity, type face and more.

public class MainActivity extends Activity {
    
     @Override
     public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
         
        ToolTip.Builder builder = new ToolTip.Builder(this, mTextView, mRootLayout, "Tip message", ToolTip.POSITION_ABOVE);
        builder.setAlign(ToolTip.ALIGN_LEFT);
        builder.setBackgroundColor(getResources().getColor(R.color.colorOrange));
        builder.setGravity(ToolTip.GRAVITY_RIGHT);
        builder.setTextAppearance(R.style.TooltipTextAppearance); // from `styles.xml`
        builder.setTypeface(mCustomFontTypeface);
    }
}

Here is an example on how you can define your text appearance in your styles.xml

<style name="TooltipTextAppearance">
    <item name="android:textColor">@color/your_custom_color</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textStyle">bold</item>
</style>

You can also customize the animation used to show and hide the tooltip view by providing ToolTipAnimator implementation and setting it in the ToolTipsManager.

public class MainActivity extends Activity {
    ToolTipsManager mToolTipsManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        mToolTipsManager = new ToolTipsManager();
        mToolTipsManager.setToolTipAnimator(MyCustomToolTipAnimator());
    }

}

Use ToolTipManger to show the tip

IMPORTANT: This must be called after the layout has been drawn You can override the onWindowFocusChanged() of an Activity and show there, Start a delayed runnable from onStart(), react to user action or any other method that works for you

public class MainActivity extends Activity {
    
    @Override
     public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
         
        ToolTip.Builder builder = new ToolTip.Builder(this, mTextView, mRootLayout, "Tip message", ToolTip.POSITION_ABOVE);
        
        // Rest of builder configurations removed for brevity
      
        mToolTipsManager.show(builder.build());
    }
}

Each tip is dismissable by clicking on it, if you want to dismiss a tip from code there are a few options, the most simple way is to do the following

public class MainActivity extends Activity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        
        mDismissBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mToolTipsManager.findAndDismiss(mTextView);
            }
        });
    }
    
}

Where mTextView is the same view we asked to position a tip near it

If you want to react when tip has been dismissed, Implement ToolTipsManager.TipListener interface and use appropriate ToolTipsManager constructor

public class MainActivity extends Activity implements ToolTipsManager.TipListener {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        mToolTipsManager = new ToolTipsManager(this);
    }

    @Override
    public void onTipDismissed(View view, int anchorViewId, boolean byUser) {
        Log.d(TAG, "tip near anchor view " + anchorViewId + " dismissed");
    
        if (anchorViewId == R.id.text_view) {
            // Do something when a tip near view with id "R.id.text_view" has been dismissed
        }
    }
    
}
