打电话

case R.id.bt_call:
                Intent intent = new Intent();
                intent.setAction(Intent.ACTION_CALL);
                intent.setData(Uri.parse("tel:"+"13218913357"));
                startActivity(intent);
                break;

brower

 case R.id.bt_browser:
                Intent intent1 = new Intent();
                intent1.setAction(Intent.ACTION_VIEW);
                intent1.setData(Uri.parse("https://www.runoob.com/design-pattern/design-pattern-intro.html"));
                startActivity(intent1);

vedio

 case R.id.bt_video:
                Intent intent2 = new Intent();
                intent2.setAction(MediaStore.ACTION_VIDEO_CAPTURE);
                startActivityForResult(intent2,101);
                break;

用VedioView播放

 if (requestCode == 101 && resultCode == Activity.RESULT_OK){
            Uri data1 = data.getData();
            vv.setVideoURI(data1);
            vv.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    vv.start();
                }
            });
        }

 case R.id.bt_tuku:
                Intent intent3 = new Intent();
                intent3.setAction(Intent.ACTION_PICK);
                intent3.setType("image/*");
                startActivityForResult(intent3,102);
                break;

用ImageView显示

else  if (requestCode == 102 && resultCode == Activity.RESULT_OK){
            Uri data1 = data.getData();
            iv.setImageURI(data1);
        }

case R.id.bt_jietu:
                View decorView = getWindow().getDecorView();
                decorView.setDrawingCacheEnabled(true);
                decorView.buildDrawingCache();
                Bitmap drawingCache = decorView.getDrawingCache();
                iv.setImageBitmap(drawingCache);

                try {
                    drawingCache.compress(Bitmap.CompressFormat.PNG,100,new FileOutputStream("/sdcard/DCIM/Camera/"+createName()+".png"));
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
