[英]How to capture a complete view of an Activity Screen in Android
我在我的活動中使用滾動視圖。我想分享整個活動屏幕但不能這樣做。能夠共享屏幕的可見部分而不是活動的全屏。是否可以采取完整活動的屏幕截圖。我試過這樣但是它只分享了活動的可見部分 .Plz幫我解決了這個問題。謝謝你
ShareImageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//View v1 = getWindow().getDecorView();
View v1 = findViewById(android.R.id.content);
v1.setDrawingCacheEnabled(true);
myBitmap = v1.getDrawingCache();
saveBitmap(myBitmap);
}
});
保存截圖::
public void saveBitmap(Bitmap bitmap) {
String filePath = Environment.getExternalStorageDirectory()
+ File.separator + "Pictures/screencapture.png";
File imagePath = new File(filePath);
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
share(filePath);
} catch (FileNotFoundException e) {
Log.e("exception1", e.getMessage(), e);
} catch (IOException e) {
Log.e("exception2", e.getMessage(), e);
}
}
try this:
public static Bitmap loadBitmapFromView(View v, int width, int height) {
Bitmap b = Bitmap.createBitmap(width , height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height);
v.draw(c);
return b;
}
