在上一个笔记里已经把IjkVideoView改造成简版的轮子了，现在来写符合自己需求的控制器。
我本次项目中主要写了以下功能：开始、暂停、调整播放进度、全屏、退出全屏等。
首先得创建自己的控制器布局文件：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.AppCompatImageButton
android:id="@+id/btn_play"
android:layout_width="@dimen/dp48"
android:layout_height="@dimen/dp48"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@color/transparent"
android:scaleType="centerInside"
android:src="@mipmap/pause" />
<android.support.v7.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@color/black_dark"
android:gravity="center_vertical"
android:orientation="horizontal"
android:paddingBottom="@dimen/dp4"
android:paddingLeft="@dimen/dp10"
android:paddingRight="@dimen/dp10"
android:paddingTop="@dimen/dp4">
<android.support.v7.widget.AppCompatTextView
android:id="@+id/tv_start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="00:00"
android:textColor="@color/white"
android:textSize="@dimen/sp12" />
<android.support.v7.widget.AppCompatSeekBar
android:id="@+id/seek_bar"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="@dimen/dp10"
android:paddingRight="@dimen/dp10" />
<android.support.v7.widget.AppCompatTextView
android:id="@+id/tv_end"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="00:00"
android:textColor="@color/white"
android:textSize="@dimen/sp12" />
<android.support.v7.widget.AppCompatCheckBox
android:id="@+id/btn_full"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dp10"
android:background="@drawable/full_screen"
android:button="@null"
android:checked="false" />
</android.support.v7.widget.LinearLayoutCompat>
</RelativeLayout>
然后定义自己的控制器。控制器需要实现 IMediaController接口。循规蹈矩的完成IMediaController各个方法的功能后，就可以添加自己的方法了。不啰嗦，直接贴代码：
package com.wym.mario.widget.media;
import android.content.Context;
import android.media.AudioManager;
import android.os.Handler;
import android.os.Message;
import android.support.v7.widget.AppCompatCheckBox;
import android.support.v7.widget.AppCompatImageButton;
import android.support.v7.widget.AppCompatSeekBar;
import android.support.v7.widget.AppCompatTextView;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.CompoundButton;
import android.widget.MediaController;
import android.widget.SeekBar;
import com.wym.mario.R;
import tv.danmaku.ijk.media.player.IMediaPlayer;
import java.util.Locale;

private static final int SET_VIEW_HIDE = 1;

private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {

switch (msg.what) {

//自定义的接口，可以根据自己的需求修改
private OnVideoListener mListener;
public void setListener(OnVideoListener listener) {
mListener = listener;
}
public interface OnVideoListener {
void onPause(boolean pause);
void onFullScreen(boolean full);
}
}
最后就是如何在项目中使用了。比较建议使用代码创建IVideoView，附上我自己的初始化代码：
video = new IVideoView(this);
video.setVideoUrl("视频地址");
controller = new MyMediaController(this);
controller.setListener(new MyMediaController.OnVideoListener() {
@Override
public void onPause(boolean pause) {
}
@Override
public void onFullScreen(boolean full) {
LinearLayoutCompat parent = (LinearLayoutCompat) video.getParent();
if (full) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
//做自己想做的操作
} else {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
//做自己想做的操作
}
}
});
controller.attach(video);
video.setMediaController(controller);
video.setBackgroundColor(getResources().getColor(R.color.black));
video.setLoop(false); // 设置不循环播放
video.setLayoutParams(new LinearLayoutCompat.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
llParent.addView(video);
video.start();
另外需要处理一下进入后台，重新回到前台和界面销毁的一些操作：
@Override
protected void onResume() {
super.onResume();
if (video != null) {
video.seekTo(lastPosition);
video.resume();
}
}
@Override
protected void onPause() {
super.onPause();
if (video != null && video.isPlaying()) {
lastPosition = video.getCurrentPosition();
video.pause();
}
}
@Override
public void onBackPressed() {
if (controller.isFull()) {
controller.switchFull(false);
} else {
super.onBackPressed();
}
}
@Override
protected void onDestroy() {
if (video != null && video.isDrawingCacheEnabled()) {
video.destroyDrawingCache();
}
if (controller != null) {
controller.disAttach(video);
}
IjkMediaPlayer.native_profileEnd();
super.onDestroy();
}
到此结束。
