How to get String from Intent?

问题

I wrote some code to get text from the EditView, put it in the Intent Extras and set it in a TextView on other Activity.

Here is my code from the sending Activity

Intent intent = new Intent(MyLayoutActivity.this, LayoutForOneActivity.class);
intent.putExtra("CaptionOne", String.valueOf(txt_caption1.getText()));
startActivity(intent);

And here is the code from my receiving Activity

Intent intent1 = getIntent();
Bundle bundle = intent1.getExtras();

if (bundle != null) {
    caption = bundle.getString("CaptionOne");
}

If try to run this code I get the ClassCastException looking like this:

java.lang.ClassCastException: android.text.SpannableString cannot be cast 
to java.lang.String

回答1:

use

intent.putExtra("CaptionOne", txt_caption1.getText().toString);

instead of

intent.putExtra("CaptionOne", String.valueOf(txt_caption1.getText()));

and also datatype of caption should be String

回答2:

use

Intent i = getIntent();
String Data = i.getStringExtra("Data");
