首先是添加权限
<uses-permission
android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
tools:ignore="ProtectedPermissions" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.WRITE_APN_SETTINGS"
tools:ignore="ProtectedPermissions" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Xml布局的规划
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<SurfaceView
android:id="@+id/surfaceView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="@+id/biaoti"
android:textColor="@color/colorAccent"
android:textSize="20sp"
android:text="< 视频播放"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<ImageView
android:id="@+id/imageView"
android:layout_centerInParent="true"
android:src="@mipmap/ic_launcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:id="@+id/linear"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="60dp"
android:orientation="horizontal">
<Button
android:id="@+id/play"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="play" />
<Button
android:id="@+id/pasue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="pasue" />
<Button
android:id="@+id/stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="stop" />
</LinearLayout>
<SeekBar
android:layout_above="@id/linear"
android:id="@+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
定义一个MyClickListener.java，用来对控件的点击和双击的判断和使用
public class MyClickListener implements View.OnTouchListener {
private static int timeout=400;//双击间四百毫秒延时
private int clickCount = 0;//记录连续点击次数
private Handler handler;
private MyClickCallBack myClickCallBack;
public interface MyClickCallBack{
void oneclick();//点击一次
void doubleClick();//点击两次
}
public MyClickListener(MyClickCallBack myClickCallBack){
this.myClickCallBack=myClickCallBack;
handler=new Handler();
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction()==MotionEvent.ACTION_DOWN){
clickCount++;
handler.postDelayed(new Runnable() {
@Override
public void run() {
if (clickCount==1){
myClickCallBack.oneclick();
}else if (clickCount==2){
myClickCallBack.doubleClick();
}
handler.removeCallbacksAndMessages(null);
clickCount=0;
}
},timeout);
}
return false;
}
}
最后是MainActivity的写入
public class MainActivity extends AppCompatActivity implements View.OnClickListener, MyClickListener.MyClickCallBack {
private SurfaceView mSurfaceView;
private Button mPlay;
private Button mPasue;
private Button mStop;
private SurfaceHolder surfaceHolder;
private MediaPlayer mediaPlayer;
