我在我的模拟器应用程序上使用android studio完美运行。
但是，当我开始使用真实设备（三星Galaxy S4和Galaxy S6）时，应用程序已启动，但当我点击该按钮时，它将停止工作。
这是我的代码：
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(2) == 3) {
left.setImageResource(R.drawable.ace);
}
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);
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) {
left.setImageResource(R.drawable.seven);
} else if (cards.get(2) == 3) {
left.setImageResource(R.drawable.ace);
}
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);
Toast.makeText(MainActivity.this, "Guessed!", Toast.LENGTH_SHORT).show();
}
}
});
}
}

按钮new game正常工作，但当我点击任何一张卡片时游戏崩溃。（左，中，右）

首先你应该编辑你的问题而不是添加答案，然后把它放在你的清单文件中的应用程序标签中
