如果我想在这个类中添加一个按钮以便我可以调用onclicklistener
,我应该怎么做?我还提供了我要添加这个视图的活动类。
活动:
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.RelativeLayout;
import android.content.Context;
public class NewGame extends Activity {
View view;
Context context;
RelativeLayout layout;
GameView gameview;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
gameview=new GameView(this);
setContentView(gameview);
//layout = (RelativeLayout) findViewById(R.id.relative_layout);
//layout.addView(gameview);
}
}
视图:公共类 GameView 扩展视图 { 路径圈;油漆 cPaint;油漆 tPaint;字符串 z; int i = 65,strt,arc,leftx,topy,rightx,bottomy,maxx,maxy;布尔标志1,标志2,标志3;双 n1, n2; 整数 n, n3 = 180,n4,n5 = 90; 浮动 f1 = 180,f2 = 90;按钮 b1; 随机 r = new Random(); RectF 椭圆形;
public GameView(Context context) {
super(context);
leftx = 0;
topy = 60;
rightx = 150;
bottomy = 120;
z = String.valueOf(Character.toChars(i));
cPaint = new Paint();
cPaint.setColor(Color.RED);
strt = 45;
arc = 315;
n1 = Math.random() * 600;
Log.d("random", z);
if (flag2 == false)
new DrawThread(this);
// cPaint.setStrokeWidth(2);
tPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
tPaint.setStyle(Paint.Style.FILL_AND_STROKE);
tPaint.setColor(Color.BLACK);
float scale = getResources().getDisplayMetrics().scaledDensity;
tPaint.setTextSize(20 * scale);
}
public void onSizeChanged(int w,int h,int oldh,int oldw) {
maxx = oldw;
maxy = oldh;
}
//@Override
protected void onDraw(Canvas canvas) {
// Drawing commands go here
oval = new RectF(leftx,topy,rightx,bottomy);
canvas.drawArc(oval, strt, arc, true, cPaint);
while (i < 90) {
canvas.drawText(String.valueOf(Character.toChars(i)),f1,f2, tPaint);
break;
}
}
}
