java - 如何将文本从活动传递到另一个？

Question

我要上第一个Activity（在layout里写）你叫什么名字？！当一个人在电影中写下他的名字时，它应该出现 Hello(THE NAME)！我该怎么做？

Answer 1

这就是您使用参数调用意图的方式

Intent search = new Intent(FirstActivity.this, SecondActivity.class);
search.putExtra("param_a", content1);
startActivity(search);

Answer 2

public class MainActivity extends Activity {
     @Override
    public void onCreate(Bundle savedInstanceState) {
          //some stuff

          //Note : start the activity from an event (onClick per example)
          String stringObject = "Foo"; //or a String you get from your editText
          Intent i = new Intent(MainActivity.this, OtherActivity.class);
           i.putExtra("name", stringObject);
           startActivity(i);
     }
}



public class OtherActivity extends Activity {
         @Override
        public void onCreate(Bundle savedInstanceState) {
              //some stuff

               Bundle extras = getIntent().getExtras(); 
               String name = "";

               if (extras != null){
                name = extras.getString("name");
                myTextView.setText(name);
              }

         }
    }
