我在我的模擬器應用程序上使用android studio時效果很好。當按下按鈕時，應用程序崩潰
但是，當我開始在真實設備（三星Galaxy S4和Galaxy S6）上啓動應用程序，但是當我點擊按鈕時，它停止工作。
這裏是我的代碼：
ImageView left, middle, right;
List<Integer> cards;
Button newGame;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cards = new ArrayList<>();
cards.add(1); // 5 of diamonds
cards.add(2); // 7 of diamonds
cards.add(3); // 1 of spades
Collections.shuffle(cards);
newGame = (Button)findViewById(R.id.btnNewGame);
left = (ImageView) findViewById(R.id.ivCardLeft);
middle = (ImageView) findViewById(R.id.ivCardMiddle);
right = (ImageView) findViewById(R.id.ivCardRight);
newGame.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Collections.shuffle(cards);
left.setImageResource(R.drawable.cardback);
middle.setImageResource(R.drawable.cardback);
right.setImageResource(R.drawable.cardback);
Animation animLeft = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.left);
Animation animMiddle = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.middle);
Animation animRight = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.right);
left.startAnimation(animLeft);
middle.startAnimation(animMiddle);
right.startAnimation(animRight);
}
});
left.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (cards.get(2) == 1) {
left.setImageResource(R.drawable.five);
} else if (cards.get(2) == 2) {
left.setImageResource(R.drawable.seven);
} else if (cards.get(2) == 3) {
left.setImageResource(R.drawable.ace);
Toast.makeText(MainActivity.this, "Guessed!", Toast.LENGTH_SHORT).show();
}
if (cards.get(1) == 1) {
middle.setImageResource(R.drawable.five);
} else if (cards.get(1) == 2) {
middle.setImageResource(R.drawable.seven);
} else if (cards.get(1) == 3) {
middle.setImageResource(R.drawable.ace);
}
if (cards.get(0) == 1) {
right.setImageResource(R.drawable.five);
} else if (cards.get(0) == 2) {
right.setImageResource(R.drawable.seven);
} else if (cards.get(0) == 3) {
right.setImageResource(R.drawable.ace);
}
}
});
middle.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (cards.get(2) == 1) {
left.setImageResource(R.drawable.five);
} else if (cards.get(2) == 2) {
left.setImageResource(R.drawable.seven);

} else if (cards.get(1) == 3) {
middle.setImageResource(R.drawable.ace);
Toast.makeText(MainActivity.this, "Guessed!", Toast.LENGTH_SHORT).show();
}
if (cards.get(0) == 1) {
right.setImageResource(R.drawable.five);
} else if (cards.get(0) == 2) {
right.setImageResource(R.drawable.seven);
} else if (cards.get(0) == 3) {
right.setImageResource(R.drawable.ace);
}
}
});
right.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (cards.get(2) == 1) {
left.setImageResource(R.drawable.five);
} else if (cards.get(2) == 2) {

把你的logcat錯誤 –
你可以真正得到的logcat設備也 –
我連接星系S4我有一些問題與S6 –
