[ANDROID]用canvans.drawText寫字

ShowAnActivity.java

package bear.Graphis.showan;

import android.app.Activity;
import android.os.Bundle;

public class ShowAnActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);
     
        DrawView drawView =new DrawView(this);
        setContentView(drawView);
    }
}

DrawView.java

package bear.Graphis.showan;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;

public class DrawView extends View {

 public DrawView(Context context) {
  super(context);
  // TODO Auto-generated constructor stub
 }

 @Override
 protected void onDraw(Canvas canvas) {
  // TODO Auto-generated method stub
  super.onDraw(canvas);
  Paint mypaint =new Paint();
  mypaint.setTextSize(45);//設定字體大小
  mypaint.setColor(Color.LTGRAY );//設定字體顏色
  canvas.drawText("豆漿加紅茶", 0, 40, mypaint);//（顯示文字,顯示位置-X,顯示位置-Y, paint）
 }
