如何从Intent中获取String？ [英] How to get String from Intent?

问题描述

我写了一些代码从EditView中获取文本，将其放在Intent Extras中，然后在其他Activity的TextView中进行设置。

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.

这是我发送活动的代码

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

这是我接收活动中的代码

And here is the code from my receiving Activity

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

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

如果尝试运行此代码，我将得到如下所示的ClassCastException：

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

推荐答案

使用

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

而不是

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

以及标题的数据类型也应为字符串

and also datatype of caption should be String
