Android 我的实用程序类应该扩展什么?
您好,我正在创建一个外部jar文件,这是一个用于重塑文本视图的库,下面是重塑类:Android 我的实用程序类应该扩展什么?,android,class,utility,Android,Class,Utility,您好,我正在创建一个外部jar文件,这是一个用于重塑文本视图的库,下面是重塑类: public class Reshaper extends Activity{ public static Context co; public static void ReshapeTextview(TextView Textview, String fontpath) { Typeface tf = Typeface.createFromAsset(co.getAssets()
public class Reshaper extends Activity{
public static Context co;
public static void ReshapeTextview(TextView Textview, String fontpath) {
Typeface tf = Typeface.createFromAsset(co.getAssets(), fontpath);
Textview.setTypeface(tf);
PersianReshape.reshape(Textview.getText().toString());
}
下面是我在其他项目中如何使用它,我已经在那里导入了这个jar
public class Main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = (TextView) findViewById(R.id.textView1);
Reshaper.ReshapeTextview(tv, "title.TTF");
}
但当我发射它的时候,我得到了一个力量接近
下面是日志:

不要让它扩展任何内容,在静态方法中接受
上下文
作为参数
您可能可以执行以下操作:
public class Reshaper {
public static void ReshapeTextview(TextView Textview, String fontpath) {
Context co = Textview.getContext();
ReshapeTextview(Textview, fontpath, co);
}
// If the Context returned is not the correct one, you can accept a context as a parameter:
public static void ReshapeTextview(TextView Textview, String fontpath, Context co) {
Typeface tf = Typeface.createFromAsset(co.getAssets(), fontpath);
Textview.setTypeface(tf);
PersianReshape.reshape(Textview.getText().toString());
}
}
就您看到的错误而言,注释是正确的,因为找不到类
整形器
,这意味着它不在类路径中。整形器不需要活动的行为。因此,不要扩展任何内容。您还有其他类型的问题:VM找不到整形器类。@Leonidos我按照本教程导出了jar文件!你错过了一些东西,你的罐子不在你的apk里或者它在错误的地方)你能解释一下你的答案吗?
