java - 将使用 radiogroup 做出的选择转移到另一个 Intent

Question

我在 Main3Activity 中有 4 个单选组(比如几个是或否)，我希望将这些选择发送到另一个 Intent (Main4Activity)。我使用 Button12 来更改 Intent 。

我尝试执行此代码

public class Main3Activity extends AppCompatActivity {
int snoring = 0;
int pressure = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main3);
    Button btnNew = (Button) findViewById(R.id.button12);


    btnNew.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {
            Intent intent = new Intent(Main3Activity.this, Main4Activity.class);
            if(snoring == 1) {intent.putExtra("snoring", "1");} else {intent.putExtra("snoring", "0");}
            if(pressure == 1) {intent.putExtra("pressure", "1");} else {intent.putExtra("pressure", "0");}
            startActivity(intent);
        }


    });

}

public void onRadioButtonClicked(View view) {

    // Is the button now checked?
    boolean checked = ((RadioButton) view).isChecked();

    // Check which radio button was clicked
    switch(view.getId()) {
        case R.id.radioButton1:
            if (checked)
                snoring = 1;
                break;
        case R.id.radioButton2:
            if (checked)
                snoring = 0;
                break;
        case R.id.radioButton3:
            if (checked)
                pressure = 1;
                break;
        case R.id.radioButton4:
            if (checked)
                pressure = 0;
                break;
    }
}

}

在下一个 Intent 中，我尝试使用与此类似的方法显示结果:

 String snoring = getIntent().getExtras().getString("snoring");
 String pressure= getIntent().getExtras().getString("pressure");

但是“打鼾”和“压力”始终为0。如何从之前的 Intent 中恢复打鼾和压力数据？

    Just do-:

     btnNew.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                Intent intent = new Intent(Main3Activity.this, Main4Activity.class);
                 intent.putExtra("snoring",snoring);   //value that came from radio button
                 intent.putExtra("pressure",pressure) //value that came from radio button
                startActivity(intent);
            }


      });

and on other activity-:

if(intent.hasEXtra("snoring))
{
get the snoring value
}

else if(intent.hasEXtra("pressure))
{
get the pressure value
}
