Probe

Dissect layout traversals on Android.

Features

Intercept View methods.
- onMeasure(int, int)
- onLayout(boolean, int, int, int, int)
- draw(Canvas) and onDraw(Canvas)
- requestLayout()
Override any of these methods on-the-fly.
Layout debugging:
- OvermeasureInterceptor: Tints views according to the number of times they got measured in a single traversal.
- LayoutBoundsInterceptor: Equivalent to Android's "Show layout bounds" developer option. The main difference being that you can show bounds only for specific views.

Usage

Add buildscript dependency:

buildscript {

  ...
  dependencies {

...

classpath 'org.lucasr.probe:gradle-plugin:0.1.3'
  
}
 
}

Apply the plugin to your app’s build.gradle:

apply plugin: 'org.lucasr.probe'

Enable Probe on a build variant:

probe {

  buildVariants {

debug {

 enabled = true

}

  
}
 
}

Implement an Interceptor:

public class DrawGreen extends Interceptor {

  private final Paint mPaint;

public DrawGreen() {

mPaint = new Paint();

mPaint.setColor(Color.GREEN);

  
}

@Override
  public void onDraw(View view, Canvas canvas) {

canvas.drawPaint(mPaint);

  
}
 
}

Deploy your Interceptor with an (optional) Filter:

public final class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {

Probe.deploy(this, new DrawGreen(), new Filter.ViewId(R.id.view2));

super.onCreate(savedInstanceState);

setContentView(R.id.main_activity);

  
}
 
}
