如何膨胀一个的LinearLayout（对于Android键盘）？ [英] How to inflate a LinearLayout ( for android keyboard )?

问题描述

我想创建一个Android键盘，现在我希望它只是夸大，即显示，从main.xml中的LinearLayout

I'm trying to create an android keyboard, right now I want it just to inflate, i.e. show, linearlayout from main.xml

下面是java文件

package keyboard.rob.com;

import ...

public class zyz extends InputMethodService 
implements KeyboardView.OnKeyboardActionListener {

    private KeyboardView mInputView;

    @Override public void onCreate() {
        super.onCreate();
    }

    @Override public View onCreateInputView() {
        mInputView = (KeyboardView) getLayoutInflater().inflate(R.layout.main, null);
        return mInputView;
    }
}

main.xml中

main.xml

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_gravity="center" android:id="@+id/LL_whole" android:orientation="vertical" android:clickable="false">


    <LinearLayout android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:background="@layout/backrep" android:layout_gravity="center" android:id="@+id/LL_total" android:orientation="vertical" android:layout_height="wrap_content">
        <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:background="@drawable/spell_frame" android:layout_marginBottom="10px" android:layout_marginTop="5px" android:layout_gravity="center" android:id="@+id/LL_spell" android:paddingLeft="10px">
        </LinearLayout>


        <LinearLayout android:layout_height="wrap_content" android:orientation="horizontal" android:layout_gravity="center" android:layout_width="wrap_content" android:id="@+id/LLrow1">

        </LinearLayout>
        <LinearLayout android:layout_height="wrap_content" android:layout_gravity="center" android:orientation="horizontal" android:layout_width="wrap_content" android:id="@+id/LLrow2"></LinearLayout>
        <LinearLayout android:layout_height="wrap_content" android:layout_gravity="center" android:orientation="horizontal" android:layout_width="wrap_content" android:id="@+id/LLrow3"></LinearLayout>
        <LinearLayout android:layout_height="wrap_content" android:layout_gravity="center" android:orientation="horizontal" android:layout_width="wrap_content" android:id="@+id/LLrow4">
        </LinearLayout>

    </LinearLayout>


</LinearLayout>

和错误它崩溃了：

08-29 20:21:28.128: ERROR/AndroidRuntime(10227): java.lang.ClassCastException: android.widget.LinearLayout

任何想法？谢谢！

public class TotalKeyboard extends InputMethodService 
implements KeyboardView.OnKeyboardActionListener {

    private LinearLayout mInputView;

    @Override public void onCreate() {
        super.onCreate();
    }

    @Override public View onCreateInputView() {
        mInputView = (LinearLayout) getLayoutInflater().inflate(R.layout.main, null);
        return mInputView;
    }
}
