¿Cómo tomar la captura de pantalla de la página de actividad ENTERO mediante programación?

Una forma es extraer el mapa de bits de la pantalla actual y guardarlo. Prueba esto:

public void takeScreenshot(){ Bitmap bitmap = getScreenBitmap(); // Get the bitmap saveTheBitmap(bitmap); // Save it to the external storage device. } public Bitmap getScreenBitmap() { View v= findViewById(android.R.id.content).getRootView(); v.setDrawingCacheEnabled(true); v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); v.buildDrawingCache(true); Bitmap b = Bitmap.createBitmap(v.getDrawingCache()); v.setDrawingCacheEnabled(false); // clear drawing cache return b; } 

Android toma la captura de pantalla mediante programación

Esta es una forma de tomar "captura de pantalla" de una vista. No lo he probado para decir si funciona

 //View v is the root view/parent of your layout, for example LinearLayout or RelativeLayout (layout where you have placed content of which you want to take screenshot) private Bitmap getBitmapFromView(View v) { Bitmap bitmap = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas (bitmap); v.draw(canvas); // Returns screenshot return bitmap; } 

Public class MainActivity extends Actividad {

 ImageView imageView = null; ScrollView sv = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); sv = (ScrollView) findViewById(R.id.ssscrollView); imageView = (ImageView) findViewById(R.id.imgView); Button myBtn = (Button) findViewById(R.id.btn); myBtn.setOnClickListener(new View.OnClickListener() { @SuppressWarnings("deprecation") @Override public void onClick(View v) { View v1 = sv.getRootView(); v1.setDrawingCacheEnabled(true); Bitmap bm = getBitmapFromView(v1); @SuppressWarnings("deprecation") BitmapDrawable bitmapDrawable = new BitmapDrawable(bm); ImageView view2 = (ImageView) findViewById(R.id.imgView); view2.setBackgroundDrawable(bitmapDrawable); } }); } private Bitmap getBitmapFromView(View v) { Bitmap bitmap = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); v.draw(canvas); return bitmap; } 

}
