我将尝试尽可能详细地解释问题，但由于这是一个非常具体的问题，这将很难。但我已经完成了我的选择，并且真的不知道如何解决这个问题。
我正在创建一款Android游戏，用户可以按照正确的顺序点击图片，以进入下一个级别。我在屏幕上的随机位置生成这些图像，当用户点击图像时，它应该触发事件。在Android 4.0及更高版本上，这非常有效。但是，当我在较低版本上测试时，图像的位置似乎是正确的，但是当点击图像时，它会为不同的图像触发事件，或者根本不触发图像。此外，当您单击一个空白区域（通常位于左上角）时，它也会触发一个事件。我不确定它是低Android版本还是低屏幕分辨率。
代码
BubbleImage XML
这是图像的布局，onClickEvent直接设置为RelativeLayout而不是relativelayout中的ImageView
<?xml version="1.0" encoding="utf-8"?>
<com.timkranen.customui.BubbleImage xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/bubImgMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/bubbleImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:src="@drawable/bubble_selector" />
<TextView
android:id="@+id/numberTxtView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/bubbleImage"
android:layout_alignLeft="@+id/bubbleImage"
android:layout_alignBottom="@+id/bubbleImage"
android:layout_alignRight="@+id/bubbleImage"
android:gravity="center"
android:text="test"
android:textColor="#fff"
android:textSize="23sp" />

生成随机BubbleImages
对不起这里的长片代码，我应该提一下，我使用ninoldandroid库来获得正确的 旧版Android上的x / y坐标（ViewHelper类执行此操作）：
private void generateRandomView(int amount) {
LayoutInflater inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i <= amount; i++) {
// add imageview to layout
BubbleImage rImg = (BubbleImage) inflater.inflate(
R.layout.bubbleimage, null);
rImg.setEnabled(false);
rImg.setOnClickListener(new BubbleClick());
bubbleImages.add(rImg);
totalBubbles++;
// create random number in between amount and 0
int genNum = this.generateRandomNum(amount);
rImg.setNumber(genNum);
numbers.add(genNum);
// determine the screen size
screenSize = getScreenSize();
screenSize.x = screenSize.x - screenSize.x / 4;
screenSize.y = screenSize.y - ((screenSize.x / 4) * 3) + 20;
// stick might throw a stackoverflow error if its called too much
// but the game only needs to call it on level max
// stackoverflowerror @ 10x on 300x300
// stackoverflowerror @ 16x on 250x250
// depends on screen size
Point randomLoc = null;
try {
Random random = new Random();
randomLoc = generateRandomLocation(screenSize, random);
} catch (StackOverflowError e) {
Toast.makeText(
this,
"BrainTest PRO encountered a fatal error caused by low memomory on your device. Restart the app and try again, if the error persists please report it to the developer.",
Toast.LENGTH_LONG).show();
finish();
}
Resources r = getResources();
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(180,
180);
mainLayout.addView(rImg, params);
ViewHelper.setTranslationX(rImg, (float) randomLoc.x);
ViewHelper.setTranslationY(rImg, (float) randomLoc.y);
// scalefactor on basis of screensize
float scaleFactor = 1.2f;
ViewHelper.setScaleX(rImg, scaleFactor);
ViewHelper.setScaleY(rImg, scaleFactor);
生成随机位置方法
我认为我不需要澄清generateRandomNum（）但我必须澄清这个方法，它是一个递归方法，进入循环直到生成的图像不再碰撞
private Point generateRandomLocation(Point dimensions, Random random) {
// generate random x
int x = random.nextInt((dimensions.x - 0) + 1);
// generate random y
int y = random.nextInt((dimensions.y - 0) + 1);
Point location = new Point(x, y);
if (!collision(location)) {
return new Point(x, y);
} else {
return generateRandomLocation(dimensions, new Random());
}
}
BubbleClick事件 这是事件发生，事件本身有效，但不会在正确的位置点火
private class BubbleClick implements OnClickListener {
private ScoreCalculator calculator;
public BubbleClick() {
calculator = new ScoreCalculator();
}
@Override
public void onClick(View arg0) {
BubbleImage clicked = (BubbleImage) arg0;
Log.d("Clicked_bubble", "Num: " + clicked.getNumber() + " | X: " + ViewHelper.getTranslationX(clicked) + " | Y: " + ViewHelper.getTranslationY(clicked));
ImageView clicked_img = (ImageView) clicked
.findViewById(R.id.bubbleImage);
if (currentClick == clicked.getNumber()) {
if (previousBub != null) {
GameActivity.this.drawLine(clicked);
}
// SUCCESFULL CLICK
score += calculator.pointsPerBubble(currentLevel);
scoreLabel.setText("Score: " + String.valueOf(score));
// clicked_img.setImageResource(R.drawable.bubble_ok);
clicked.setEnabled(false);
previousBub = clicked;
playPosSound();
for (int i = 0; i <= clicked.getChildCount(); i++) {
View child = clicked.getChildAt(i);
if (child instanceof TextView) {
TextView txtView = (TextView) clicked.getChildAt(i);
txtView.setVisibility(View.VISIBLE);
}
}
// check wether the last bubbleimage was clicked
if (countListClick + 1 != numbers.size()) {
countListClick++;
currentClick = numbers.get(countListClick);
} else {
GameActivity.this.resetGame(true);
}
} else {
// WRONG ATTEMPT
clicked_img.setImageResource(R.drawable.bubble_wrong);
scores.add(new Score(score, attempt));
attempt++;
if (attempt > 3) {
// GAME OVER
isGameOver = true;
continueBut.setVisibility(View.INVISIBLE);
GameActivity.this.gameOver();
}
previousBub = null;
playNegSound();
if (currentLevel > 0) {
currentLevel--;
}
vibrate();
for (int i = 0; i <= clicked.getChildCount(); i++) {
View child = clicked.getChildAt(i);
if (child instanceof TextView) {
TextView txtView = (TextView) clicked.getChildAt(i);
txtView.setVisibility(View.VISIBLE);
}
}
// show all text and disable buttons
if (bubbleImages != null) {
for (BubbleImage bImg : bubbleImages) {
bImg.setEnabled(false);
for (int i = 0; i <= bImg.getChildCount(); i++) {
View childV = bImg.getChildAt(i);
if (childV instanceof TextView) {
TextView childView = (TextView) childV;
childView.setVisibility(View.VISIBLE);
}
}
}
}
if (!isGameOver) {
GameActivity.this.resetGame(false);
}
// GAME OVER
}
}
onClickListener的内容非常无关紧要，因为代码运行正常而不是在正确的时刻。有谁知道发生了什么事？
提前致谢！
答案 0 :(得分：1)
因为这对我来说是一个真正的问题：
ViewHelper.getTranslation方法在2.x上的行为与在4.x上的行为不同，我使用的是Margins。
