Android:如何发送超过一个变量的意图？

Question

我正在从main.java发送几个变量

    Bundle bund = new Bundle();
    Intent intent = new Intent(this, newWindow.class);
    String name = editName.getText().toString();
    bund.putString(yourName, name);
    String pass= editPassword.getText().toString();
    bund.putString(yourPass,pass);
    String mail=EditMail.getText().toString();
    bund.putString(yourMail,mail);
    intent.putExtras(bund);
    startActivity(intent);

转到newWindow.java

        Intent intent = getIntent();
        Bundle extras =  intent.getExtras();
           String name = extras.getString(main.yourName);
           String mail = extras.getString(main.yourMail);
           String pass = extras.getString(main.yourPass);
        viewText1 = (TextView) findViewById(R.id.textView2);
        viewText2 = (TextView) findViewById(R.id.textView3);
        viewText3 = (TextView) findViewById(R.id.textView4);
        viewText1.setText(name);
        viewText2.setText(mail);
        viewText3.setText(pass);

问题是，只有最后一个变量被传递并显示在所有三个文本视图的中

Answer 1

想必，您在所有情况下都使用相同的密钥。换句话说，yourName的值与yourPass的值相同，后者与yourMail的值相同。这些都需要有独特的价值。通常，我们将static final String键用于Bundle。

为什么不避开捆绑部分呢？

简单地在FirstActivity中，尝试如下

Intent intent = new Intent(this, NewWindow.class);
String name = editName.getText().toString();
String pass= editPassword.getText().toString();
String mail=EditMail.getText().toString();
intent.putExtra("name",name);
intent.putExtra("mail",mail);
intent.putExtra("pass",pass);
startActivity(intent);

然后在RecievingActivity中这样做

Intent extras=getIntent();
String name = extras.getStringExtra("name");
String mail = extras.getStringExtra("mail");
String pass = extras.getStringExtra("pass");
viewText1.setText(name);
viewText2.setText(mail);
viewText3.setText(pass);
