我的主要课程是这样的:
package projects.game.spinners;
import java.util.ArrayList;
import java.util.Collections;
import android.os.Bundle;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.view.Menu;
public class MainActivity extends Activity
{
public Set set;
public Deal deal= new Deal();
public Player Name = new Player();
public computer comp1= new computer();
public computer comp2= new computer();
public computer comp3= new computer();
private Table table;
public Canvas canvas;
//public ArrayList<Domino> deck = set.getSet();
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
set = new Set(this);
table = new Table(this);
ArrayList<Domino> deck = set.getSet();
canvas = new Canvas();
Collections.shuffle(deck);
//deal.deal(Name, comp1, comp2, comp3, deck);
//deck = deal.getDeck();
table.playDomino(deck.get(0), 0, 0);
table.invalidate();
//table.onDraw(this);
//Bitmap dsd = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
我的ondraw方法在table中,它看起来像这样:
package projects.game.spinners;
import java.util.ArrayList;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.view.View;
import android.widget.Toast;
public class Table extends View
{
ArrayList<Position> table;
Context ctx;
Bitmap draw;
public Table(Context context)
{
super(context);
ctx=context;
table=new ArrayList<Position>();
draw = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
this.setWillNotDraw(false);
}
public int getPossiblePlays()
{
return 0;
}
public void playDomino(Domino domino, int x , int y)
{
table.add(new Position(domino,x,y));
}
@Override
public void onDraw(Canvas canvas)
{
super.onDraw(canvas);
Toast.makeText(ctx,"Tag Already Done", Toast.LENGTH_LONG).show();
canvas.drawBitmap(draw, 0,0, null);
canvas.drawBitmap(table.get(0).getDomino().getImage(), 0,0, null);
}
}
当这个运行时,没有什么是Draw。我希望能够一遍又一遍地绘制这个,因为我改变应该绘制的内容,如果有任何其他方法可以做到这一点,不使用无可调用的类。
答案 0 :(得分:0)
似乎表格尚未添加到正在绘制的任何内容中。在主要活动的onCreate中尝试这样的事情:
table = new Table(this);
RelativeLayout layout = (RelativeLayout) findViewById(R.id.IdOfYourMainLayoutFromYourManifest);
layout.addView(table);
