android - 在 Android 中使用 Gama 组件

Question

我想在 Android 中使用 Gama 组件来使我们的应用程序变得更好。我已经下载了 Gama 的 jar，即使它抛出错误。我已经点击了以下链接 http://developer.digitalaria.com/devguide/gama/en/gama/tile_android.php .

Java

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import com.digitalaria.gama.tile.Tile;

public class GamaAndroidActivity extends Activity {
    Button button;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

}

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <com.digitalaria.gama.tile.Tile
        android:id="@+id/tile"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

Answer 1

错误说

android.view.InflateException: Binary XML file line #7: Error inflating class com.digitalaria.gama.tile.Tile

这意味着您在声明的 xml 文件中的第 7 行有错误com.digitalaria.gama.tile.Tile 所以检查该类是否可用。

在您使用 xml 文件的类(class)中:

 import com.digitalaria.gama.tile.Tile;

编辑:

要添加 Gama 库，请将其从 javaBuildpath 中移除并改为执行以下操作:

 1. Create a new folder, libs, in your Eclipse/Android project.
 2. Right-click libs and choose Import -> General -> File System, then
    Next, Browse in the filesystem to find the library's parent
    directory and add your GAMA jar.
 3. Right-click on your project, choose Build Path -> Configure Build
    Path, then click the Libraries tab, then Add JARs..., navigate to
    your new JAR in the libs directory and add it.
 4. Clean the project
