略仿今日头条部分功能,只供参考,娱乐而已(图片3秒跳转,无限轮播,webview,tablayout,listview,Xlistview)

涉及到的知识点有

1.自定义控件，重写控件的相关方法

  实现：

  （1）频道管理（带拖拽，动画）Android 高仿 频道管理----网易、今日头条、腾讯视频 （可以拖动的GridView）附源码DEMO

  （2） 新闻列表中每个字段按照时间进行排列，并且带有悬浮效果

  （3）城市选择列表中的城市信息按照首字母进行排列，并且带有悬浮效果

注意：（1）通过重写GridView。（2）和（3）通过重写ListView，之后通过接口判断是否在最最上方了，进行状态变更，DEMO的代码中可以清晰看懂

2.SQLITE数据库的使用

  实现：保存用户设置的频道信息

3.Activity之间的动画跳转方式

4.Animation动画类的相关知识

  实现：频道管理中频道的移动动画

5.WebView的相关知识和 jsoup库解析HTML

  实现：新闻详情的查看、排版，图片信息的提取。（这块没深入研究，知识从别人那边借鉴了点放进去的）

6.重写ViewPager和ImageView

  实现：图片浏览和通过手势放大缩小

7.GestureDetector手势类及OnGestureListener手势监听类的使用

  实现：新闻详情页面根据手势滑动来关闭该页面

------------------------------主Activity就是一张图片几秒后跳转

public class MainActivity extends AppCompatActivity {

    private TextView text_view;
    private Button button_tiyan;
    int time = 3;
    private Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
        super.handleMessage(msg);
        if (msg.what == 0){
            if (time > 0){
                time --;
                text_view.setText(time + "秒后进入");
                handler.sendEmptyMessageDelayed(0 , 1000);
            }else{
                Intent intent = new Intent(MainActivity.this , SecondActivity.class);
                startActivity(intent);
                finish();
            }
        }
        }
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        text_view = (TextView) findViewById(R.id.text_view);
        button_tiyan = (Button) findViewById(R.id.button_tiyan);

	//点击按钮跳转
        button_tiyan.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this , SecondActivity.class);
                startActivity(intent);
                finish();
            }
        });

	//发送
        handler.sendEmptyMessageDelayed(0 , 1000);
    }
    @Override
    protected void onPause() {
        super.onPause();
        handler.removeMessages(0);
    }
}

------------------------------第二个Activity主要是fragment之间的切换(点击按钮,fragment切换,没有滑动的效果注意)

布局这个radio_group按钮,(这里的按钮是图片)改变背景的xml

public class SecondActivity extends AppCompatActivity {

    private RadioGroup group;
    private List list = new ArrayList<>();
    private FragmentManager manager;
    private Fragment_shou fragment_shou;
    private Fragment_two fragment_two;
    private Fragment_my fragment_my;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        group = (RadioGroup) findViewById(R.id.radio_group);
        manager = getSupportFragmentManager();
        fragment_shou = new Fragment_shou();
        manager.beginTransaction().add(R.id.fragme_layout , fragment_shou).commit();

        group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int i) {
                FragmentTransaction transaction = manager.beginTransaction();

                if (fragment_shou != null){
                    transaction.hide(fragment_shou);
                }
                if (fragment_two != null){
                    transaction.hide(fragment_two);
                }
                if (fragment_my != null){
                    transaction.hide(fragment_my);
                }

                switch (i){
                    case R.id.button_01:
                        if (fragment_shou == null){
                            fragment_shou = new Fragment_shou();
                            transaction.add(R.id.fragme_layout , fragment_shou);
                        }else{
                            transaction.show(fragment_shou);
                        }
                        break;
                    case R.id.button_02:
                        if (fragment_two == null){
                            fragment_two = new Fragment_two();
                            transaction.add(R.id.fragme_layout , fragment_two);
                        }else{
                            transaction.show(fragment_two);
                        }
                        break;
                    case R.id.button_03:
                        if (fragment_my == null){
                            fragment_my = new Fragment_my();
                            transaction.add(R.id.fragme_layout , fragment_my);
                        }else{
                            transaction.show(fragment_my);
                        }
                        break;

                    default:
                        break;
                }
                transaction.commit();
            }
        });
    }
}

************build.gradle的一部分    只供参考    注意要把26改为25

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.+'
    compile 'com.android.support:design:25.3.1'	     <--!tablayout-->
    compile 'com.google.code.gson:gson:2.8.1'        <--!gson-->
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'  <--!imageload-->
}

*1.去标题   在style里面建一个

<style name="NoTitleTheme" parent="Theme.AppCompat.Light.NoActionBar">

style>
*2.然后在清单里调用,这样是全部都去标题,可以谁去谁调用他
android:theme="@style/NoTitleTheme"
