public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

private class DrawView extends View {

Paint myPaint = null;

public DrawView(Context context) {
super(context);
setWillNotDraw(false);

myPaint = new Paint();
myPaint.setFlags(Paint.ANTI_ALIAS_FLAG);

}

@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
System.out.println("-------------------");
canvas.drawColor(Color.WHITE);
myPaint.setColor(Color.BLACK);
canvas.drawText("张欣爱我一万年", 40, 40, myPaint);

}

}

}

你没有使用下面的DrawView类啊，尝试一下下面的方法，其他不用改 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); View view=new DrawView(this); setContentView(view); }
