Java 使用方法更改变量，然后无法将值分配给另一个变量

我有一个方法将一个变量（声明为=0）更改为一个整数（例如：10），然后我想将这个整数分配给另一个变量（int-playeronicon）

某些活动

：

public class SomeActivity extends AppCompatActivity implements View.OnClickListener {

Integer playerOneIcon= 0, playerIcon = 0;

onCreate(Bundle savedInstanceState) {

Button btn_test = findViewById(R.id.btn_test);
    btn_test.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(ii_PlayerSetting.this, String.valueOf(playerOneIcon), Toast.LENGTH_SHORT).show();
        }
    });

}

ShowPop1(View v) {  }
//Will paste it below

ShowPop2(View v) {  }
//Will paste it below

public void onClick(View v){     }
//Will paste it below

}

当用户单击某个按钮时，“ShowPop1（视图v）”将运行，它将调用一个弹出对话框，从而调用以下内容中的onClick（）

ShowPop1（视图五）

ShowPop1(View v) {
playerIcon = playerOneIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerOneIcon = playerIcon;
}

ShowPop2(View v) {
playerIcon = playerTwoIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerTwoIcon = playerIcon;
}

onClick(v){
playerIcon = 10;
ChangeHeadDialog.dismiss();
//if i put "playerOneIcon = playerIcon;" here, it will work, but I can't since it may be playerTwoIcon that should assign instead

}

ShowPop2（视图五）

ShowPop1(View v) {
playerIcon = playerOneIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerOneIcon = playerIcon;
}

ShowPop2(View v) {
playerIcon = playerTwoIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerTwoIcon = playerIcon;
}

onClick(v){
playerIcon = 10;
ChangeHeadDialog.dismiss();
//if i put "playerOneIcon = playerIcon;" here, it will work, but I can't since it may be playerTwoIcon that should assign instead

}

onClick（v）

ShowPop1(View v) {
playerIcon = playerOneIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerOneIcon = playerIcon;
}

ShowPop2(View v) {
playerIcon = playerTwoIcon;

ChangeHeadDialog.setContentView(R.layout.somelayout);

onClick(v);

playerTwoIcon = playerIcon;
}

onClick(v){
playerIcon = 10;
ChangeHeadDialog.dismiss();
//if i put "playerOneIcon = playerIcon;" here, it will work, but I can't since it may be playerTwoIcon that should assign instead

}

然后，当我按下btn_测试时，结果是0。请帮助，非常感谢！

我通过在showpop1（）和showPop2（）中添加一个变量，然后在onClick（）中运行一个方法解决了这个问题

ShowPop1（视图五）

ShowPop2（视图五）

applyPlayerIconToPlayer（整型playerIcon）

在onClick（）内运行applyPlayerIconToPlayer（整数playerIcon）：

完成！

你在哪里打印“PlayerOnicon”？到其他帖子可能就是你要找的for@PrashanthVerma为了更好地理解，编辑了这个问题，谢谢！您是在showPop1（）之前还是之后调用Toast？请将整个代码放在showPop1（）之后？@PrashanthVerma.哦，你想知道更多的是哪一部分？我可以试试，但恐怕这将是一个庞大的代码行。。。
