Err apk应用程序正在关闭

Question

我的程序写随机文章，这在屏幕上工作，没有问题。

添加应用程序共享按钮后，应用程序直接关闭。你能检查一下代码吗?谢谢你！我认为问题出在"公共空股"上。部分

这个错误以前不存在。自从我添加共享(无效共享)代码以来，这个错误就一直存在。我无法解决这个错误。我在等待你的帮助。

Answer 1

您点击的动作代码将是paylas(View view)而不是paylas(String title, String content)

所以你需要把你的代码替换成下面的代码。

public class MainActivity extends Activity {
..............

public void paylas(View view) {
String title = "Share"; // you need get title in here.
String content = tw1.getText().toString(); // this is new
// Create an ACTION_SEND Intent
Intent intent = new Intent(Intent.ACTION_SEND);
// Set the type of the content to "text"
intent.setType("text/plain");
// Adding extras to the intent (title & content) 
intent.putExtra(Intent.EXTRA_SUBJECT, title);
intent.putExtra(Intent.EXTRA_TEXT, content);
startActivity(Intent.createChooser(intent, title));
}
}

PS:

如果你需要，从textView中获取内容，你可以这样做

String text = tw1.getText().toString();
