项目现在已经差不多稳定了，总结自己这段时间的经历。
公司的项目是一款配合路由器的app，但是说到底其实都一样，只是在取数据的时候把网络，换成了一个路由器。公式的项目哗哗Wifi ，主要做的是视频以及免费上网。

（4）然后就是进行音量调节，快进，快退亮度的调节，使用手势监听就能实现这一点
<span style="white-space:pre"> </span>mGestureDetector = new GestureDetector(new MyGestureListener());然后就是在onTouch 跟onScroll 里边进行处理；
现在我是把屏幕分成平均的俩分，如果是在左边滑动，而且没有在快进回事快退的时候就是调整亮度，反之就是调整音量。
在调整进度的时候是不能调整亮度的，我加了这判断，而且视频只有在快进已经快退完成以后才进行视频的seekTo（）。
/** 滑动 */
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
mMediaController.hide();
float mOldX = e1.getX(), mOldY = e1.getY();
int y = (int) e2.getRawY();
int x = (int) e2.getRawX();
Display disp = getWindowManager().getDefaultDisplay();
int windowWidth = disp.getWidth();
int windowHeight = disp.getHeight();
if (Math.abs(x- mOldX) >20 && !isUp_downScroll) { //执行快进快退
isFast_Forword = true;
mFast_forward = x - mOldX;
fast_ForWord(mFast_forward);
}else if (mOldX > windowWidth * 1.0 / 2 && Math.abs(mOldY - y) > 3 && !isFast_Forword)// 右边滑动
onVolumeSlide((mOldY - y) / windowHeight);
else if (mOldX < windowWidth / 2.0 && Math.abs(mOldY - y) > 3 && !isFast_Forword)// 左边滑动
onBrightnessSlide((mOldY - y) / windowHeight);
return super.onScroll(e1, e2, distanceX, distanceY);
}
/**
* 滑动改变声音大小
*
* @param percent
*/
private void onVolumeSlide(float percent) {
isUp_downScroll = true;
if (mVolume == -1) {
mVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
if (mVolume < 0)
mVolume = 0;
// 显示
mOperationBg.setImageResource(R.drawable.video_volumn_bg);
mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
}
int index = (int) (percent * mMaxVolume) + mVolume;
if (index > mMaxVolume)
index = mMaxVolume;
else if (index < 0)
index = 0;
// 变更声音
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, index, 0);
// 变更进度条
ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
lp.width = findViewById(R.id.operation_full).getLayoutParams().width * index / mMaxVolume;
mOperationPercent.setLayoutParams(lp);
}
调整亮度：
/**
* 滑动改变亮度
*
* @param percent
*/
private void onBrightnessSlide(float percent) {
isUp_downScroll = true;
if (mBrightness < 0) {
mBrightness = getWindow().getAttributes().screenBrightness;
if (mBrightness <= 0.00f)
mBrightness = 0.50f;
if (mBrightness < 0.01f)
mBrightness = 0.01f;
// 显示
mOperationBg.setImageResource(R.drawable.video_brightness_bg);
mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
}
WindowManager.LayoutParams lpa = getWindow().getAttributes();
lpa.screenBrightness = mBrightness + percent;
if (lpa.screenBrightness > 1.0f)
lpa.screenBrightness = 1.0f;
else if (lpa.screenBrightness < 0.01f)
lpa.screenBrightness = 0.01f;
getWindow().setAttributes(lpa);
ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
lp.width = (int) (findViewById(R.id.operation_full).getLayoutParams().width * lpa.screenBrightness);
mOperationPercent.setLayoutParams(lp);
}
在手势进行快进快退的时候让时间进行改变：
private void fast_ForWord(float dis){
long currentProgress ;
long duration = mVideoView.getDuration();
if (mVideoView.getCurrentPosition() + 500*(long)dis < 0)
currentProgress = 0;
else
currentProgress = mVideoView.getCurrentPosition() + 500*(long)dis;
mTv_progress.setText(Utils.generateTime(currentProgress) + "/" + Utils.generateTime(duration));
if (dis > 0)
mIv_Progress_bg.setImageResource(R.drawable.btn_fast_forword);
else
mIv_Progress_bg.setImageResource(R.drawable.btn_back_forword);
mFl_Progress.setVisibility(View.VISIBLE);
} @Override
public boolean onTouchEvent(MotionEvent event) {
if (mGestureDetector.onTouchEvent(event))
return true;
// 处理手势结束
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
endGesture();
break;
}
return super.onTouchEvent(event);
}
/** 手势结束 */
private void endGesture() {
mVolume = -1;
mBrightness = -1f;
if (isFast_Forword) {
onSeekProgress(mFast_forward);
}
// 隐藏
mDismissHandler.removeMessages(0);
mDismissHandler.sendEmptyMessageDelayed(0, 800);
} <span style="white-space:pre"> </span>onSeekProgress（long）是调整进度的：<pre name="code" class="java"> private void onSeekProgress(float dis){
Log.e("position ==", mVideoView.getCurrentPosition() + 500*(long)dis+"/"+mVideoView.getDuration());
mVideoView.seekTo(mVideoView.getCurrentPosition() + 500*(long)dis);
}
以上就是里边比较关键的些部分，博客只是为了自己记录。
Demo就不发了。
