package com.example.administrator.myapplication;

import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

import com.xys.libzxing.zxing.activity.CaptureActivity;
import com.xys.libzxing.zxing.encoding.EncodingUtils;

public class MainActivity extends AppCompatActivity {
ImageView iv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv = (ImageView) findViewById(R.id.show);
    }

    public void onclick(View view) {
        Intent intent = new Intent(this,CaptureActivity.class);
        startActivityForResult(intent,200);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode==200&&resultCode ==RESULT_OK){
            String result = data.getStringExtra("result");
            Toast.makeText(this, ""+result, Toast.LENGTH_SHORT).show();
        }
    }

    public void onclick2(View view) {
        Bitmap bit = BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher);
        Bitmap bitmap1 = EncodingUtils.createQRCode("他是我的",200,200,bit);
        iv.setImageBitmap(bitmap1);

        // 获取  内容及二维码图片的  生成Bitmap  logo为 二维码中间的  图片展示  1/5大小
//        Bitmap bitmap1 = EncodingHandler.enCodeStringWithLogo("多个亲戚不算多！", this, bitmap, 400);
    }
