在点击按钮以外的其他活动上显示文本

Question

我知道如何在同一页面上单击按钮来显示文本，但是我的问题是（由于我在Google上找不到任何内容）：单击按钮时，是否有可能在其他活动中显示文本？

Answer 1

Yes, you can

In your FirstActivity execute this when button is clicked:

Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("data","Messsage to be sent");
startActivity(intent);

In your SecondActivity inside onCreate() :

String someData = getIntent().getStringExtra("data");
yourTextView.setText(someData);

Answer 2

You can use Intent for this. Intent is used to move on other activity from first activity.

You can use :

Intent i = new Intent(MainActivity.this,SecondActivity.class);
        i.putExtra("YourValueKey", yourData.getText().toString());

then you can get it from your second activity by :

Intent intent = getIntent();
String YourtransferredData = intent.getExtras().getString("YourValueKey");

Answer 3

If you need pass values between the activities you use this:

 String name="aaaa";
 Intent intent=new Intent(Main_Activity.this,Other_Activity.class);
 intent.putExtra("name", name);
 startActivity(intent);

And this code to recovery data on new Activity:

Bundle b = new Bundle();
b = getIntent().getExtras();
String name = b.getString("name");
