产品功能介绍：
1、应用查找
2、广告应用分析
3、广告应该卸载
4、白名单设置
开始从头来介绍代码：
欢迎界面：WelComeActivity.java
package com.eoe.adskiller; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.animation.AlphaAnimation; import android.view.animation.Animation; import android.view.animation.Animation.AnimationListener; import android.widget.ImageView; public class WelComeActivity extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.welcome_layout); ImageView image=(ImageView)findViewById(R.id.imageView551); // AlphaAnimation类是Android系统中的透明度变化动画类 // [基本语法】public AlphaAnimation (float fromAlpha, float toAlpha) // 参数说明:fromAlpha：开始时刻的透明度，取值范围0~1。toAlpha：结束时刻的透明度，取值范围0~1。 AlphaAnimation alphaAnimation=new AlphaAnimation(1, 1); alphaAnimation.setDuration(1000); //设置持续时间 alphaAnimation.setAnimationListener(new AnimationListener() { @Override public void onAnimationStart(Animation animation) { // TODO 自动生成的方法存根 } @Override public void onAnimationRepeat(Animation animation) { // TODO 自动生成的方法存根 } @Override public void onAnimationEnd(Animation animation) { // TODO 自动生成的方法存根 Intent intent = new Intent(); intent.setClass(WelComeActivity.this, MainActivity.class); startActivity(intent); finish(); } }); image.startAnimation(alphaAnimation); } }
显示效果图：
让后接入主机面：
MainActivity.java代码如下：
package com.eoe.adskiller; import java.util.List; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup.LayoutParams; import android.widget.Button; import android.widget.ImageView; import android.widget.LinearLayout; public class MainActivity extends Activity { private static final String TAG = "com.eoe.adskiller.MainActivity"; private Button scanbtn,setbtn; private ImageView myimg; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); scanbtn = (Button)findViewById(R.id.check); setbtn = (Button)findViewById(R.id.setting); myimg=(ImageView)findViewById(R.id.imageView1); // 屏幕宽（像素，如：480px） int screenHeight = getWindowManager().getDefaultDisplay().getHeight(); myimg.setMaxHeight(screenHeight-568); scanbtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO 自动生成的方法存根 Intent scanIntent=new Intent(MainActivity.this,ScanResult.class); MainActivity.this.startActivity(scanIntent); // Log.d("start scan activity", "start time"); } }); setbtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO 自动生成的方法存根 Intent setIntent=new Intent(MainActivity.this,SettingActivity.class); MainActivity.this.startActivity(setIntent); } }); } }
SettingActivity.Java 这里不附录代码了！
ScanResult.java 代码如下：
package com.eoe.adskiller; import java.util.ArrayList; import java.util.List; import android.R.integer; import android.app.Activity; import android.content.pm.PackageInfo; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.util.Log; import android.view.View; import android.widget.BaseAdapter; import android.widget.ListView; import android.widget.ProgressBar; import android.widget.RelativeLayout; import android.widget.TextView; import android.widget.Toast; public class ScanResult extends Activity { ListView rlListView; ProgressBar mProgressBar; TextView scaning,scanended; @Override protected void onCreate(Bundle savedInstanceState) { // TODO 自动生成的方法存根 super.onCreate(savedInstanceState); setContentView(R.layout.activity_result); rlListView=(ListView)findViewById(R.id.listview); mProgressBar=(ProgressBar)findViewById(R.id.progressBar); scaning=(TextView)findViewById(R.id.textscan); scanended=(TextView)findViewById(R.id.scanend); Handler backHandler=new TaskHandler(this); ScanTask myScanTask=new ScanTask(this,backHandler); myScanTask.setPriority(Thread.MAX_PRIORITY); myScanTask.start(); // Log.d("activity create","create time"); } @Override protected void onStart() { // TODO 自动生成的方法存根 super.onStart(); } @Override protected void onResume() { // TODO 自动生成的方法存根 super.onResume(); } class TaskHandler extends Handler { private ScanResult parentActivityResult=null; ArrayList<AppInfo> appList = new ArrayList<AppInfo>(); AppAdapter appAdapter; private int count =0; public TaskHandler (ScanResult result) { parentActivityResult=result; } @Override public void handleMessage(Message msg) { // TODO 自动生成的方法存根 super.handleMessage(msg); if (msg.what==0) { AppInfo tmpInfo = new AppInfo(); tmpInfo=(AppInfo)msg.obj; if (count==0) { appList.add(tmpInfo); appAdapter=new AppAdapter(ScanResult.this,appList); rlListView.setDividerHeight(5); if(rlListView!=null) { rlListView.setAdapter(appAdapter); } } else { appAdapter.dataList.add(tmpInfo); appAdapter.notifyDataSetChanged(); } count++; } else { setProgressBarVisibility(false); mProgressBar.setVisibility(View.GONE); scaning.setVisibility(View.GONE); scanended.setVisibility(View.VISIBLE); } } } }
package com.eoe.adskiller; import java.util.ArrayList; import android.R.raw; import android.content.Context; import android.content.Intent; import android.net.Uri; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.ImageButton; import android.widget.ImageView; import android.widget.TextView; public class AppAdapter extends BaseAdapter { Context context; ArrayList<AppInfo> dataList=new ArrayList<AppInfo>(); public AppAdapter(Context context,ArrayList<AppInfo> inputDataList) { this.context=context; dataList.clear(); for(int i=0;i<inputDataList.size();i++) { dataList.add(inputDataList.get(i)); } } @Override public int getCount() { // TODO Auto-generated method stub return dataList.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return dataList.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { View v=convertView; final AppInfo appUnit=dataList.get(position); if(v==null) { LayoutInflater vi=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); v=vi.inflate(R.layout.app_row, null); v.setClickable(true); } TextView appName=(TextView)v.findViewById(R.id.appName); ImageView appIcon=(ImageView)v.findViewById(R.id.icon); Button btnButton=(Button)v.findViewById(R.id.button1); if(appName!=null) { appName.setText(appUnit.appName); } if(appIcon!=null) appIcon.setImageDrawable(appUnit.appIcon); btnButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { AppInfo theApp=(AppInfo)dataList.get(position); Uri packageURI = Uri.parse("package:" +theApp.packageName); Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI); context.startActivity(uninstallIntent); } }); return v; } }
