安卓中是通过继承view重写私有onDraw方法中使用canvas实现的，autojs虽然可以访问安卓相关这些，但无法访问私有方法，也无法继承实现自定义，有什么可以解决的办法吗？
以下为使用onDraw(Canvas canvas)画矩形区域，及在其上画文本的实例（通过使用内部类使程序显得更加简洁，紧凑）：
package com.android.test; 链接文本
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.View;
public class TestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new TestView(this));
}
public class TestView extends View {
private Paint mPaint = new Paint();
public TestView(Context context) {
super(context);
}
@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
String text = "Android - 机器人";
mPaint.setColor(Color.WHITE);
Paint paint = new Paint();
paint.setColor(Color.RED);
String familyName = "宋体";
Typeface font = Typeface.create(familyName,Typeface.BOLD);
paint.setTypeface(font);
paint.setTextSize(22);
canvas.drawRect(new Rect(0, 0, 320, 240), mPaint);
canvas.drawText(text, 0, 100, paint);
}
}
}
