java - 如何仅传递用户选择的字符串

Question

当我单击按钮时，我需要该按钮仅传递选定的字符串。

如果整数为 2，我尝试传递特定字符串。

显示这是我的第一个名为 PlayerChoose 的 Activity :

    //PI1 and PI2 is Strings from another Activity.
    PI1 = getIntent().getStringExtra("Player1Text");
    PI2 = getIntent().getStringExtra("Player2Text");

    //These bellow are buttons.
    Player1Btn = findViewById(R.id.PlayerToD1);
    Player2Btn = findViewById(R.id.PlayerToD2);

    //These Integers is to set 0 so the app is not broken.
    PlayerInt1 = 0;
    PlayerInt2 = 0;

    //Here im setting text to the buttons so you know what player you pick
    Player1Btn.setText(PI1);
    Player2Btn.setText(PI2);

    //These button adds 1 to the Integer PlayerInt1 so if you hit it 
    //twice it executes what is in the if statement.
    Player1Btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PlayerInt1++;
            if (PlayerInt1 == 2) {
    Intent TruthOrDare1 = new Intent(PlayerChoose.this,TruthOrDare.class);
                TruthOrDare1.putExtras(getIntent());
                TruthOrDare1.putExtra("Player1Text", PI1);
                startActivity(TruthOrDare1);
            }
        }
    });
    //Same button as Player1Btn Does the same things.
    Player2Btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PlayerInt2++;
            if (PlayerInt2 == 2) {
    Intent TruthOrDare2 = new Intent(PlayerChoose.this,TruthOrDare.class);
                TruthOrDare2.putExtras(getIntent());
                TruthOrDare2.putExtra("Player2Text", PI2);
                startActivity(TruthOrDare2);
            }
        }
    });

    }
 }

这是我的第二个 Activity ，名为“TruthOrDare”:

    //PI1 Should take what i passed with "Player1Text" and save it as a 
    //String
    //PI2 Should take what i passed with "Player2Text" and save it as a 
    //String
    PI1 = getIntent().getStringExtra("Player1Text");
    PI2 = getIntent().getStringExtra("Player2Text");


    //PlayerTurnName1 and PlayerTurnName2 is textviews 
    PlayerTurnName1 = findViewById(R.id.PlayerTurnText1);
    PlayerTurnName2 = findViewById(R.id.PlayerTurnText2);

    //Here i set text to textview whatever have been passes PI1 or PI2
    //Depending
    PlayerTurnName1.setText(PI1);
    PlayerTurnName2.setText(PI2);

我的问题是，仅当我在 PlayerChoose Activity 中点击 Player1Btn 时，它才传递字符串 PI1、PI2 而不是 PI1；如果我点击 Player2Btn，则传递 PI2。如果我点击 Player1Btn，则如何仅传递 PI1；如果点击 PI2，则如何仅传递 PI2。

Answer 1

您似乎有不必要的字符串

TruthOrDare1.putExtras(getIntent());
TruthOrDare2.putExtras(getIntent());

在点击监听器中，添加 PI1 和 PI2
