偏执的太偏执、 2022-08-06 13:05 230阅读 0赞

首先得要去微信的官网申请一个 appid下来

[点击打开微信官网链接][Link 1]

然后再下载微信官网里的一个签名生成工具

[点击下载签名工具][Link 2]

再按找微信官网里的教程大致做就是了

我做出来的代码是这样的

package com.baixou123.findscore.wxapi;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.graphics.Bitmap;
    import android.graphics.BitmapFactory;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.Toast;
    
    import com.baixou123.findscore.MainActivity;
    import com.baixou123.findscore.R;
    import com.tencent.mm.sdk.modelmsg.SendMessageToWX;
    import com.tencent.mm.sdk.modelmsg.WXMediaMessage;
    import com.tencent.mm.sdk.modelmsg.WXWebpageObject;
    import com.tencent.mm.sdk.openapi.IWXAPI;
    import com.tencent.mm.sdk.openapi.WXAPIFactory;
    
    public class  WXEntryActivity extends Activity {
    	private static final String APP_ID = "wx9xxxxxxxxxxx";//这是app_id
    	private IWXAPI api;
    	private Button bt1 = null;
    	private Button bt2 = null;
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		// TODO Auto-generated method stub
    		super.onCreate(savedInstanceState);
    		//setContentView(R.layout.weixin_test);
    		// 微信注册初始化
    		api = WXAPIFactory.createWXAPI(this, APP_ID, true);
    		api.registerApp(APP_ID);
    		
    		Intent in = getIntent();
    		int wei_flag = in.getIntExtra("FLAG", 0);
    
    		bt1 = (Button) this.findViewById(R.id.weixin_bt1);
    		bt2 = (Button) this.findViewById(R.id.weixin_bt2);
    
    		share2weixin(wei_flag);
    		/*bt1.setOnClickListener(new OnClickListener() {
    
    			@Override
    			public void onClick(View v) {
    				share2weixin(0);
    			}
    		});
    		bt2.setOnClickListener(new OnClickListener() {
    
    			@Override
    			public void onClick(View v) {
    				share2weixin(1);
    			}
    		});*/
    	}
    
    	public void share2weixin(int flag) {
    		// Bitmap bmp = BitmapFactory.decodeResource(getResources(),
    		// R.drawable.weixin_share);
    
    		if (!api.isWXAppInstalled()) {
    			Toast.makeText(WXEntryActivity.this, "您还未安装微信客户端",
    					Toast.LENGTH_SHORT).show();
    			return;
    		}
    
    		WXWebpageObject webpage = new WXWebpageObject();
    		webpage.webpageUrl = "http://www.baoxiu123.com/android/njtcHelper.apk";
    		WXMediaMessage msg = new WXMediaMessage(webpage);
    
    		msg.title = "推荐内江师范学院小助手";
    		msg.description = getResources().getString(
    				R.string.app_share_weixin_txt);
    		Bitmap thumb = BitmapFactory.decodeResource(getResources(),
    				R.drawable.ic_launcher);
    		msg.setThumbImage(thumb);
    		
    		SendMessageToWX.Req req = new SendMessageToWX.Req();
    		req.transaction = String.valueOf(System.currentTimeMillis());
    		req.message = msg;
    		req.scene = flag;
    		api.sendReq(req);
    	}
    }
