我试图获取目标(启动为 ImageView)id 并将整数 id 放入 switch case 中以查看相邻的 View 并比较它们的可绘制对象以确定该玩家是否获胜或游戏是否继续。我将 buttonPressed 变量初始化为 Integer,并使用 parseInt() 来获取目标的 int 值。
public void compareButton(int buttonPressed){
//int count = 0;
ImageView adjacent;
ImageView adjacentB;
switch (buttonPressed){
case R.id.imageButtonA: //this is where adjacent buttons are identified and compared
adjacent = findViewById(R.id.imageButtonB);
adjacentB = findViewById(R.id.imageButtonC);
if (target.getDrawable() == adjacent.getDrawable() && target.getDrawable() == adjacentB.getDrawable()) {
Toast.makeText(MainActivity.this, "You Win!", Toast.LENGTH_SHORT).show(); //Win condition
// } else if (target.getDrawable() == R.id.imageButtonE.getDrawable() & target.getDrawable() == R.id.imageButtonI.getDrawable()) {
//Toast.makeText(MainActivity.this, "You Win!", Toast.LENGTH_SHORT).show(); //Win condition
// } else if (target.getDrawable() == R.id.imageButtonD.getDrawable() & target.getDrawable() == R.id.imageButtonG.getDrawable()) {
//Toast.makeText(MainActivity.this, "You Win!", Toast.LENGTH_SHORT).show(); //Win condition
}
break;
case R.id.imageButtonB:
break;
出于调试目的,我不会填写每个案例。
我遇到的问题是当我运行模拟器时出现错误
Caused by: java.lang.NumberFormatException: For input string: "androidx.appcompat.widget.AppCompatImageButton{517eade VFED..C.. ...P..ID 45,381-304,628 #7f070072 app:id/imageButtonA}"
at java.lang.Integer.parseInt(Integer.java:521)
at java.lang.Integer.parseInt(Integer.java:556)
at com.example.connect3.MainActivity.switchColor(MainActivity.java:75)
这是 OnClickListener 的代码:
public void switchColor(View view) {
//Button pressed, depending on user, switch's to that users color; identify adjacent button ID's; toast player control switch
if (player == 1) {
source = findViewById(R.id.yellow);
target = findViewById(view.getId());
target.setImageDrawable(source.getDrawable());
buttonPressed = Integer.parseInt(target.toString());
compareButton(buttonPressed);
player++;
Toast.makeText(MainActivity.this, "Player 2's Turn!", Toast.LENGTH_SHORT).show();
} else {
source = findViewById(R.id.red);
target = findViewById(view.getId());
target.setImageDrawable(source.getDrawable());
buttonPressed = Integer.parseInt(String.valueOf(target));
compareButton(buttonPressed);
player--;
Toast.makeText(MainActivity.this, "Player 1's Turn!", Toast.LENGTH_SHORT).show();
}
不完全确定此时发生了什么,因为我认为我做的一切都是正确的,但显然遗漏了一些东西。任何帮助将不胜感激。
最佳答案
更改:
buttonPressed = Integer.parseInt(String.valueOf(target));
致:
buttonPressed = target.getId();
解释:您的错误表示 NumberFormatException 意味着您正在尝试从无法解析的 String 获取 int 值,或者简单来说您的字符串不包含正确的 int 值,并且您正在传递 (androidx.appcompat.widget.. .) 作为字符串,而你必须传递按钮我会
