我可以获得关于我在 Eclipse 中制作的动态壁纸的帮助吗，我收到几个 logcat 错误。我已经研究了几个小时，不知道为什么我总是强制关闭。我在“动态壁纸选择屏幕”上强制关闭。当我运行该应用程序时，我什至无法查看任何动态壁纸。 int x,y;
public void onCreate()
{
super.onCreate();
}
public void onDestroy()
{
super.onDestroy();
}
public Engine onCreateEngine()
{
return new MyWallpaperEngine();
}
class MyWallpaperEngine extends Engine
{
private final Handler handler = new Handler();
private final Runnable drawRunner = new Runnable() {
@Override
public void run() {
draw();
}
};
private boolean visible = true;
public Bitmap image1,backgroundImage;
MyWallpaperEngine()
{
// get the fish and background image references
image1 = BitmapFactory.decodeResource(getResources(),R.drawable.fish);
backgroundImage = BitmapFactory.decodeResource(getResources(),R.drawable.water);
x=-130; // initialize x position
y=200; // initialize y position
}
public void onCreate(SurfaceHolder surfaceHolder)
{
super.onCreate(surfaceHolder);
}
@Override
public void onVisibilityChanged(boolean visible)
{
this.visible = visible;
if (visible)
{
handler.post(drawRunner);
}
else
{
handler.removeCallbacks(drawRunner);
}
}
@Override
public void onSurfaceDestroyed(SurfaceHolder holder)
{
super.onSurfaceDestroyed(holder);
this.visible = false;
handler.removeCallbacks(drawRunner);
}
public void onOffsetsChanged(float xOffset, float yOffset,
float xStep, float yStep, int xPixels, int yPixels)
{
draw();
}
void draw()
{
final SurfaceHolder holder = getSurfaceHolder();
Canvas c = null;
try
{
c = holder.lockCanvas();
// clear the canvas
c.drawColor(Color.BLACK);
if (c != null)
{
// draw the background image
c.drawBitmap(backgroundImage, 0, 0, null);
// draw the fish
c.drawBitmap(image1, x,y, null);
// get the width of canvas
int width=c.getWidth();
if(x>width+100)
{
// assign initial value to start with
x=-130;
}
// change the x position/value by 1 pixel
x=x+1;
}
}
finally
{
if (c != null)
holder.unlockCanvasAndPost(c);
}
handler.removeCallbacks(drawRunner);
if (visible)
{
handler.postDelayed(drawRunner, 10);
}
}
}
现在这是我的 Logcat

最佳答案
查看错误“1085506396 字节分配内存不足”。您收到此错误的原因可能是设备内存不足或者壁纸尺寸太大。
尝试减小动态壁纸的大小或尝试使用内存较大的设备(或模拟器)。
关于java - 动态壁纸强制接近场景，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20403419/
