android - 如何从Animatedview中的AlertDialog调用 Intent ？

我有游戏，在游戏结束后，我使用带有EditText和Button的AlertDialog输入名称，最后我必须在单击按钮时将当前比分和玩家名称保存到数据库中，很好，我可以保存比分和名称。我的要求是，当我单击同一按钮时，我想更改为游戏首页的意图（HomeActivity）。

我的代码是：

public class AnimatedView extends ImageView{
String name;
static int count=0;
private Context mContext;
int x = 130;
int y = 450;
private float a,b;
private int xVelocity = 20;
private int yVelocity = 20;
private Handler h;
private final int FRAME_RATE = 25;
BitmapDrawable ball;
boolean touching;
boolean dm_touched = false;
float move=3;
int bm_x = 0, bm_y = 0, bm_offsetx, bm_offsety,bm_w,bm_h;
boolean paused;
private Paint line, ball1, background;
static int click=0;
private static final int TEXT_ID = 0;
DBCeation dbCeation;
public AnimatedView(Context context) {
    super(context);
}
public AnimatedView(Context context, AttributeSet attrs)  {
    super(context, attrs);
    mContext = context;
    h = new Handler();
}

private Runnable r = new Runnable() {
    @Override
    public void run() {
        //Log.e("game","run called");
        if(touching = true)
        invalidate();
    }
};


@Override
protected void onDraw(Canvas c) {
    BitmapDrawable ball = (BitmapDrawable) mContext.getResources().getDrawable(R.drawable.ball);
    if (x<0 && y <0) {
        //x = this.getWidth()/2;
        y = c.getHeight()/2;


    } else {
        //Log.d("s",""+xVelocity);
        Log.d("s",""+yVelocity);
        x += xVelocity;
        y += yVelocity;
        if ((x > this.getWidth() - ball.getBitmap().getWidth()) || (x < 0)) {
            xVelocity = xVelocity*-1;
        }
        if (y >( this.getHeight() - ball.getBitmap().getHeight()) ||y <0) {
            yVelocity = yVelocity*-1;
        }
    }
    c.drawBitmap(ball.getBitmap(), x, y, null);
   //Log.e("sarat",""+touching);

  if(click>=2){
  if(bm_h+y>630){

       final EditText input=new EditText(mContext);
      Toast.makeText(getContext(),"game over",Toast.LENGTH_SHORT).show();
      AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
      builder.setTitle("Game Is Over");
        builder.setMessage("Enter your Name");
         // Use an EditText view to get user input.
         input.setId(TEXT_ID);
         builder.setView(input);
         builder.setPositiveButton("save", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

                name=input.getText().toString();
                Log.d("name",""+name);
                int score=MainActivity.score;
                dbCeation=new DBCeation(mContext);
                dbCeation.insertValues(name, score);
 //this code is not working and gives compile time error
                Intent intent=new Intent(getContext(),MainActivity.class);
                                    startActivity(intent);


            }
        });
      builder.setIcon(R.drawable.ic_launcher);


      builder.show();
      x=150;
      y=200;
      xVelocity=0;
      yVelocity=0;

  }}
    if(touching){
         // Log.e("game","iftouch called called");
        h.postDelayed(r, FRAME_RATE);
        bm_w=ball.getBitmap().getWidth();
        bm_h=ball.getBitmap().getHeight();
      }
  }

最佳答案

希望对您有帮助

Intent intent=new Intent(mContext,MainActivity.class);
mContext.startActivity(intent);

否则尝试

mContext.getApplicationContext.startActivity(intent);
