Wie man den Screenshot der benutzerdefinierten Kamera in Android macht?

Question

Ich lade die Kamera in ein framelayout und ich möchte einen Screenshot machen. der Kameravorschau.

einen Screenshot zu nehmen:

public void onClick(View v) { 
    View v1 = L1.getRootView(); 
    v1.setDrawingCacheEnabled(true); 
    Bitmap bm = v1.getDrawingCache(); 
    BitmapDrawable bitmapDrawable = new BitmapDrawable(bm); 
    image = (ImageView) findViewById(R.id.ImageView011); 
    image.setBackgroundDrawable(bitmapDrawable); 

    //Bitmap bitmap = takeScreenshot(); 
    saveBitmap(bm); 
} 

den Screenshot zu speichern:

public void saveBitmap(Bitmap bitmap) { 
    File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png"); 
    FileOutputStream fos; 
    try { 
     fos = new FileOutputStream(imagePath); 
     bitmap.compress(android.graphics.Bitmap.CompressFormat.PNG, 100, fos); 
     fos.flush(); 
     fos.close(); 
    } catch (FileNotFoundException e) { 
     Log.e("GREC", e.getMessage(), e); 
    } catch (IOException e) { 
     Log.e("GREC", e.getMessage(), e); 
    } 
} 

, wenn das Bild alles ist

im Screenshot mit Ausnahme der Kamera Vorschau der Kamera gespeichert wird Lasten innerhalb eines Rahmenlayouts:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Button 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"

<ImageView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="Take Screenshot" 
android:id="@+id/ImageView011" 
/> 
</RelativeLayout> 

Was mache ich bitte falsch? Vielen Dank im Voraus :)

Answer 1

einfach Ihre Ansicht als Argument in der folgenden Methode übergeben

public Bitmap takeScreenShot(View view) { 
    view.setDrawingCacheEnabled(true); 
    view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH); 
    view.buildDrawingCache(); 
    if (view.getDrawingCache() == null) 
     return null; 
    Bitmap snapshot = Bitmap.createBitmap(view.getDrawingCache()); 
    view.setDrawingCacheEnabled(false); 
    view.destroyDrawingCache(); 
    return snapshot; 
} 

Und speichern Sie diese Bitmap nach Ihren Bedürfnissen.
