MVP登录和注册页面Activity类生成二维码异常捕获类

1.分包效果

bean包:json格式转成java代码

MVP

model层:loginModel
package com.jia.logindemo.model;

import com.google.common.io.CharStreams;
import com.google.gson.Gson;
import com.jia.logindemo.HttpCallBack;
import com.jia.logindemo.bean.JsonBean;

import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class LoginModel {
public void login(String phone, String password, final HttpCallBack httpCallBack){
//获取网址final String data = "http://www.zhaoapi.cn/user/login";//子线程解析new Thread(){@Overridepublic void run() {super.run();try {URL url = new URL(data);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod("GET");connection.setConnectTimeout(3000);int code = connection.getResponseCode();if(code == HttpURLConnection.HTTP_OK){InputStream inputStream = connection.getInputStream();String s = CharStreams.toString(new InputStreamReader(inputStream, "UTF-8"));Gson gson = new Gson();JsonBean jsonBean = gson.fromJson(s,JsonBean.class);//getCode是json数据里的数据(成功返回code)  msg同理if(jsonBean.getCode() == 0){httpCallBack.onSuccess(jsonBean.getData());}else{httpCallBack.onFailer(jsonBean.getMsg());}}} catch (Exception e) {e.printStackTrace();}}}.start();try {Thread.sleep(3000);//写死数据if(phone.equals("aaaaaa")&&password.equals("123456")){httpCallBack.onSuccess("登陆成功");}else{httpCallBack.onFailer("登陆失败");}} catch (Exception e) {e.printStackTrace();}
}

}
Presenter层LoginPresenter
package com.jia.logindemo.presenter;

import com.jia.logindemo.HttpCallBack;
import com.jia.logindemo.model.LoginModel;
import com.jia.logindemo.view.LoginView;

public class LoginPresenter {
private LoginView loginView;
private LoginModel loginModel;

public LoginPresenter(LoginView loginView) {this.loginView = loginView;loginModel = new LoginModel();
}
public void login(String phone,String password){loginModel.login(phone, password, new HttpCallBack() {@Overridepublic void onSuccess(String result) {loginView.onSuccess(result);}@Overridepublic void onFailer(String msg) {loginView.onFailer(msg);}});
}

}
HttpCallBack接口
package com.jia.logindemo;

public interface HttpCallBack {
//返回成功或失败
void onSuccess(String result);
void onFailer(String msg);
}

View层 LoginView
package com.jia.logindemo.view;

public interface LoginView {
void onSuccess(String result);
void onFailer(String msg);
}
LoginActivity
package com.jia.logindemo;

import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import com.jia.logindemo.presenter.LoginPresenter;
import com.jia.logindemo.view.LoginView;
//实现LoginView会实现LoginView里面所有的方法
public class LoginActivity extends AppCompatActivity implements LoginView {

private EditText login_number;
private EditText login_password;
private Button login;
private Button register;
private LoginPresenter loginPresenter;@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_login);initView();initListener();//实例化LoginPresenterloginPresenter = new LoginPresenter(this);
}private void initListener() {login.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {String phonenumber = login_number.getText().toString().trim();String password = login_password.getText().toString().trim();//调用loginPresenterloginPresenter.login(phonenumber,password);}});register.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(LoginActivity.this,RegisterActivity.class);startActivity(intent);}});
}private void initView() {login_number = findViewById(R.id.login_number);login_password = findViewById(R.id.login_password);login = findViewById(R.id.login);register = findViewById(R.id.register);
}
//LoginView里面的方法
@Override
public void onSuccess(String result) {//登陆成功会保存数据 第二次直接进入SharedPreferences sharedPreferences = getSharedPreferences(Constant.APP_CONFIG, Context.MODE_PRIVATE);SharedPreferences.Editor edit = sharedPreferences.edit();edit.putBoolean(Constant.IS_LOGIN,true);edit.commit();Intent intent = new Intent(this,MainActivity.class);startActivity(intent);finish();
}@Override
public void onFailer(String msg) {runOnUiThread(new Runnable() {@Overridepublic void run() {Toast.makeText(LoginActivity.this,"登录失败",Toast.LENGTH_SHORT).show();}});
}

}

注册与登陆一样 CV改名字改网址

生成二维码

build.grade文件中添加依赖
implementation ‘cn.bingoogolapple:bga-qrcode-zxing:1.3.4’

Java代码
package com.jia.logindemo;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.Toast;

import cn.bingoogolapple.qrcode.core.BGAQRCodeUtil;
import cn.bingoogolapple.qrcode.core.QRCodeView;
import cn.bingoogolapple.qrcode.zxing.QRCodeEncoder;
//添加依赖后实现QRCodeView.Delegate
public class MainActivity extends AppCompatActivity implements QRCodeView.Delegate {

private EditText erweima;
private Button bt_click;
private ImageView ivImage;@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initView();bt_click.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {onCreateQRCode();}});
}private void onCreateQRCode() {//子线程生成二维码new AsyncTask<String, Integer, Bitmap>() {@Overrideprotected Bitmap doInBackground(String... strings) {String QRCode = erweima.getText().toString().trim();//获取要生成的二维码中间的LOGOBitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);return QRCodeEncoder.syncEncodeQRCode(QRCode,BGAQRCodeUtil.dp2px(MainActivity.this,150),Color.BLACK,bitmap);}@Overrideprotected void onPostExecute(Bitmap bitmap) {super.onPostExecute(bitmap);if(bitmap!=null){ivImage.setImageBitmap(bitmap);}else{Toast.makeText(MainActivity.this,"生成二维码失败",Toast.LENGTH_SHORT).show();}}}.execute();
}private void initView() {erweima = findViewById(R.id.erweima);bt_click = findViewById(R.id.bt_click);ivImage = findViewById(R.id.ivImage);
}@Override
public void onScanQRCodeSuccess(String result) {}@Override
public void onCameraAmbientBrightnessChanged(boolean isDark) {}@Override
public void onScanQRCodeOpenCameraError() {}

}

自定义全部异常捕获类

自定义异常捕获类
package com.jia.logindemo;

import android.content.Context;
import android.os.Process;
import android.util.Log;

public class UnCatchExceptionHandler implements Thread.UncaughtExceptionHandler {

private Context context;
private Thread.UncaughtExceptionHandler exceptionHandler;//系统的默认异常处理类
private static  UnCatchExceptionHandler instance = new UnCatchExceptionHandler();//用户自定义的异常处理类
private UnCatchExceptionHandler(){}
public static UnCatchExceptionHandler getInstance(){return instance;
};
public void init(Context context){this.context = context.getApplicationContext();exceptionHandler = Thread.getDefaultUncaughtExceptionHandler();Thread.setDefaultUncaughtExceptionHandler(this);
}
@Override
public void uncaughtException(Thread t, Throwable e) {//打log判断一下是否收集到异常Log.d("-----------",e.toString());//如果系统提供了异常处理类，则交给系统去处理if(exceptionHandler!=null){exceptionHandler.uncaughtException(t,e);}else {Process.killProcess(Process.myPid());}
}

}
新建一个类继承Application

package com.jia.logindemo;

import android.app.Application;

import com.tencent.bugly.crashreport.CrashReport;

public class GenAndApplication extends Application {

@Override
public void onCreate() {super.onCreate();//使用自定义全局异常捕获类UnCatchExceptionHandler.getInstance().init(this);
}

}

把异常提交到bugly
接上面

public class GenAndApplication extends Application {

@Override
public void onCreate() {super.onCreate();UnCatchExceptionHandler.getInstance().init(this);     CrashReport.initCrashReport(getApplicationContext(),"ec2de502e2",true);
}

}

ec2de502e2是提交到bugly后自动生成的然后CV到代码里

清单文件中添加
<uses-permission android:name=“android.permission.READ_PHONE_STATE” /
<uses-permission android:name=“android.permission.INTERNET” /
<uses-permission android:name=“android.permission.ACCESS_NETWORK_STATE” /
<uses-permission android:name=“android.permission.ACCESS_WIFI_STATE” /
<uses-permission android:name=“android.permission.READ_LOGS”/
tools:ignore=“ProtectedPermissions” /

build.grade中添加
implementation ‘com.tencent.bugly:crashreport:latest.release’
//其中latest.release指代最新Bugly SDK版本号，也可以指定明确的版本号，例如2.1.9
implementation ‘com.tencent.bugly:nativecrashreport:latest.release’
//其中latest.release指代最新Bugly NDK版本号，也可以指定明确的版本号，例如3.0

添加ndk
ndk { abiFilters ‘armeabi’,‘x86’,‘armeabi-v7a’,‘x86_64’,‘arm64-v8a’ }
