我正在使用畫(huà)布在 Surface View Camera 上繪制線性布局視圖（插入點(diǎn)）。當(dāng)視圖太多時(shí)（例如：在我的情況下為 40），我遇到了一個(gè)問(wèn)題，一些視圖在移動(dòng)相機(jī)時(shí)消失了。我在這里找不到問(wèn)題。setX 和 setY 方法有什么問(wèn)題嗎？你可以在下面看到我的代碼，請(qǐng)回復(fù)它。@Overrideprotected void onDraw(Canvas canvas) {    super.onDraw(canvas);    if (currentLocation == null) {        return;    }    for (int i = 0; i < places.size(); i++) {         float[] currentLocationInECEF = LocationHelper.WSG84toECEF(currentLocation);         float[] pointInECEF = LocationHelper.WSG84toECEF(poiLoc.get(i));         float[] pointInENU = LocationHelper.ECEFtoENU(currentLocation, currentLocationInECEF, pointInECEF);        Matrix.multiplyMV(cameraCoordinateVector, 0, rotatedProjectionMatrix, 0, pointInENU, 0);        if (cameraCoordinateVector[2] < 0 && insertPoint!=null && insertPoint.getChildAt(i)!=null) {            float x = (0.5f + cameraCoordinateVector[0] / cameraCoordinateVector[3]) * canvas.getWidth();            float y = (0.5f - cameraCoordinateVector[1] / cameraCoordinateVector[3]) * canvas.getHeight();            insertPoint.getChildAt(i).setX(x - (insertPoint.getChildAt(i).getWidth()/2));            insertPoint.getChildAt(i).setY(y);            insertPoint.getChildAt(i).setVisibility(VISIBLE);        }    }}預(yù)期結(jié)果：所有視圖都應(yīng)出現(xiàn)在相機(jī)視圖中。實(shí)際結(jié)果：一些視圖在移動(dòng) Camera 和 onDrawCanvas 回調(diào)時(shí)消失。我正在使用這個(gè)庫(kù)https://github.com/dat-ng/ar-location-based-android
