吃水不忘挖坑人
感谢寻梦的原作,让我这个Android小白能成功的完成这次操作.
写在这里的话
大体的都是来自原作者的,所以就不做更多的解释,这里只是对于其中gif图片的加载做一个记录
Android部分
重写UnitySplash
public class UnitySplashSDK
{
private ImageView bgView = null;
private GifImageView gv = null;
private UnityPlayer mUnityPlayer = null;
private TextView tv = null;
private static UnitySplashSDK mInstance = null;
public static UnitySplashSDK getInstance()
{
if(null == mInstance)
{
synchronized (UnitySplashSDK.class)
{
if(null == mInstance)
mInstance = new UnitySplashSDK();
}
}
return mInstance;
}
public void onCreate(Activity activity, Bundle savedInstanceState)
{
mUnityPlayer = ((UnityPlayerActivity)activity).getUnityPlayer();
onShowSplash();
}
public void onShowSplash()
{
if(bgView != null)
return;
try {
// 设置启动内容，这里的内容可以自定义区修改，这里我加载了一个gif作为启动图标↓
bgView = new ImageView(UnityPlayer.currentActivity);
bgView.setBackgroundColor(Color.parseColor("#36c3e5"));
InputStream is = UnityPlayer.currentActivity.getAssets().open("loadBackground.png");
Bitmap bm = BitmapFactory.decodeStream(is);
bgView.setImageBitmap(bm);
bgView.setScaleType(ImageView.ScaleType.CENTER_CROP);
Resources r = mUnityPlayer.currentActivity.getResources();
mUnityPlayer.addView(bgView, r.getDisplayMetrics().widthPixels, r.getDisplayMetrics().heightPixels);
gv = new GifImageView(UnityPlayer.currentActivity);
Point p = new Point();
WindowManager wm = (WindowManager) UnityPlayer.currentActivity.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getSize(p);
gv.setMovie(UnityPlayer.currentActivity.getAssets().open("loadAnimation.gif"),p.x / 2 - 150,p.y / 2 - 300);
gv.setScaleType(ImageView.ScaleType.CENTER);
mUnityPlayer.addView(gv, r.getDisplayMetrics().widthPixels, r.getDisplayMetrics().heightPixels);
tv = new TextView(UnityPlayer.currentActivity);
tv.setTextColor(Color.WHITE);
tv.setTextSize(16);
tv.setText("请稍后,正在努力加载中...");
Log.v("test",p.x+"");
mUnityPlayer.addView(tv, r.getDisplayMetrics().widthPixels, r.getDisplayMetrics().heightPixels);
tv.setPadding(p.x / 2 - 240,p.y / 2 + 20,0, 0);
} catch (Exception e)
{
e.printStackTrace();
}
}
public void onHideSplash()
{
try {
if(bgView == null)
return;
UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
@Override
public void run()
{
mUnityPlayer.removeView(bgView);
bgView = null;
mUnityPlayer.removeView(gv);
gv = null;
mUnityPlayer.removeView(tv);
tv = null;
}
});
}catch (Exception e)
{
e.printStackTrace();
}
}
}
Gif图调用,没有获取图片的大小,和锚点的控制,需要自己计算一下位置
package com.jx.shoe;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Movie;
import android.util.AttributeSet;
import android.view.View;
import android.widget.ImageView;
import java.io.InputStream;
/**
* Created by Administrator on 2018/7/25.
*/
public class GifImageView extends ImageView
{
private Movie mMovie;
private long mMovieStart = 0;
private int x,y;
public GifImageView(Context context)
{
super(context);
}
public GifImageView(Context context, AttributeSet attrs)
{
super(context,attrs);
}
public void setMovie(InputStream is ,int dx,int dy)
{
mMovie = Movie.decodeStream(is);
x = dx;
y = dy;
}
@Override
public void onDraw(Canvas canvas) {
long now = android.os.SystemClock.uptimeMillis();
if (mMovieStart == 0) {
mMovieStart = now;
}
if (mMovie != null) {
int dur = mMovie.duration();
if (dur == 0) {
dur = 1000;
}
int relTime = (int) ((now - mMovieStart) % dur);
mMovie.setTime(relTime);
mMovie.draw(canvas, x, y);
invalidate();
}
}
}
在UnityPlayerActivity脚本的onCreate中添加如下一句
UnitySplashSDK.getInstance().onCreate(this,savedInstanceState);
还需要在这个脚本添加一个函数
public void hideSplash()
{
UnitySplashSDK.getInstance().onHideSplash();
}
Unity部分
private AndroidJavaObject m_activity;
void Awake()
{
AndroidJavaClass ajc = new AndroidJavaClass("com.jx.shoe.UnityPlayerActivity");
}
void Start () {
HideAndroidSplash();
}
public void HideAndroidSplash() {
ajc.Call("hideSplash");
}
在程序一开运行的时候就隐藏界面
ps
我这里是直接在Andorid中写了加载界面,没有使用unity的加载界面,相当于在Andorid中给加载的那一段黑屏时期给了一块遮羞布.
顺带在说一下,图片资源放在unity导出的工程的assets文件夹下,据说这种对于gif的操作在gif文件比较大的时候会报错,奈何我使用android-gif-drawable这个开源框架的时候,真机调试提示我硬件不支持该App,对于我这个小白,这个问题,我实在是不知道从何查起,只能换一种方法了,如果有大神愿意指点一下迷津,不甚感激.
不知道是不是我打开方式不对,在给unity调用隐藏的时候,需要单独写一个类供unity调用,而不能直接使用unity打包工程生成的那个UnityPlayerAcitivity,我尝试直接将这个hideSplash写在生成的这个UniytPlayerActivity里面,没法完成调用,至于为什么,当前没有明确的答案,如果有大神知道,烦请告知.
