Java 如何在片段中单击按钮时检索EditText和微调器?
我试图从EditText中获取字符串,并在片段中单击按钮时使用微调器Java 如何在片段中单击按钮时检索EditText和微调器?,java,android,android-fragments,Java,Android,Android Fragments,我试图从EditText中获取字符串,并在片段中单击按钮时使用微调器 public void buttonClick (View view) { Spinner stars = findViewById(R.id.starsSpinner); String starsText = stars.getSelectedItem().toString(); EditText time = findViewById(R.id.editTime); String tim

sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, shareBody));
}
我在一个活动中编写了一些代码,但我不知道如何更改它,使其在片段中工作
public void buttonClick (View view) {
Spinner stars = findViewById(R.id.starsSpinner);
String starsText = stars.getSelectedItem().toString();
EditText time = findViewById(R.id.editTime);
String timeText = time.getText().toString();
EditText location = findViewById(R.id.editLocation);
String locationText = location.getText().toString();
String space = " ";
String shareBody ="!r " + starsText + space + locationText + space + timeText;
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setClassName("com.discord", "com.discord.app.AppActivity$AppAction");
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, shareBody));
}
活动中的代码与discord应用程序共享一个字符串。我对碎片的每一次修改都会使应用程序崩溃
谢谢您的帮助。首先,您不能像处理活动一样一次点击一个片段 因此,您应该从xml中删除这一行:
android:onClick="someMethod"
然后在片段中初始化button对象并调用
它的setOnClickListener方法
看看这个:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView=inflater.inflate(R.layout.fragment_blank, container, false);
//using findViewById() in a Fragment
Button button=rootView.findViewById(R.id.button_id);
//handle onclick events for the button
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText time = rootView.findViewById(R.id.editTime);
}
});
return rootView;
}
我希望这能有所帮助。您的片段代码在哪里?你必须给我们提供更多的细节来帮助。加上日志中显示的错误,你真是天才。在这种格式下工作得非常好。我很高兴终于有了代码工作后,我拔出头发的年龄。非常感谢。@Steve不客气。如果答案对你有帮助,请接受
