Android应用案例--广告查查看

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);
    }

}

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！
