java - 在android中创建软键盘时出错

Question

这是我的资源文件 res/layout/input.xml。 My.application - 我的 android 程序的名称

<my.application.android.inputmethodservice.KeyboardView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/keyboard"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

Android 软键盘在此创建:

public View onCreateInputView() {
        mInputView = (KeyboardView) getLayoutInflater().inflate(R.layout.input,
                null);
        Keyboard keyboard = new Keyboard(this, R.xml.qwerty);
        mInputView.setKeyboard(keyboard);
        mInputView.setEnabled(true);
        mInputView.setPreviewEnabled(true);
        mInputView.setOnKeyboardActionListener(this);
        return mInputView;
    }

应用程序编译没有错误。当我在任何 Android 应用程序中调用我的软键盘时，我会收到下一个错误:

在 list 文件中试试这个

<activity android:label="@string/app_name" android:name="my.application.android.inputmethodservice.KeyboardView">

您不需要完全限定的类名。此外，如果您正在使用 Eclipse 并重命名一个包，请转到 Project -> Clean 并让它清理您的项目修复引用等，如果有任何损坏。
