Android 将文本设置为EditText是运行时异常

什么是ISpellCheckerSessionListener.java:61行？确保已正确初始化

etFreeText

，并且

freeText\u lastSearch

不为null。我没有使用任何拼写检查服务类或侦听器类，并且free\u lastSearch不为null。因为logcat是这么说的<代码>etFreeText是否正确初始化？在xml中检查其id一次。

EditText etFreeText = (EditText)pw.getContentView().findViewById(R.id.etSearch);

btnPopUpSearch.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

etFreeText.setText(freeText_lastSearch.toString());

            });
