篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Metail Design各个控件相关的知识,希望对你有一定的参考价值。

前言:

   SDK更新的历史上几个特别重要的版本144.0194.4215.0,这是有差异的就放到各自的版本中,没有差异的就放到value中,这里是版本兼容开发.

举个列子:

  这里底部导航栏的颜色属性只有5.x以上才有,所以最好写到values-21里面

<!--底部导航栏颜色,这里只有5.x以上的才能设置,所以最好放到API 21里,低于这个的不起作用-->
<item name="android:navigationBarColor">@color/colorPrimaryDark</item>

 

Metail Design代表控件:

1.android.support.v7.app.AlertDialog

效果比AlertDialog好看点,如图:

 

2.风格可以尽量用AppCompat类型的风格:

1 <ProgressBar
2  android:layout_width="match_parent"
3  android:layout_height="wrap_content"
4  style="@style/Widget.AppCompat.ProgressBar.Horizontal"
5  android:id="@+id/progressbar_horizontal"
6  android:max="100"
7  android:progress="80"
8  />

 

 style="@style/Widget.AppCompat.ProgressBar.Horizontal"就是采用的材料风格

 

 

 3.android.support.v4.widget.SwipeRefreshLayout

 

最好里面包裹一层 ScrollView,这样才有滑动效果,一下是简单用法

 

mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                Log.i(TAG, "onRefresh: 进行中......."+Thread.currentThread().getName());
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        try {
                            Thread.currentThread().sleep(3000);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                mSwipeRefreshLayout.setRefreshing(false);
                            }
                        });
                    }
                }).start();
            }
        });
        mSwipeRefreshLayout.setSize(SwipeRefreshLayout.LARGE);
        mSwipeRefreshLayout.setColorSchemeColors(Color.RED,Color.GREEN,Color.BLUE);
        mSwipeRefreshLayout.setProgressBackgroundColorSchemeColor(Color.YELLOW);
        mSwipeRefreshLayout.setDistanceToTriggerSync(110);

 

 

 4.LinearLayoutCompat

 替代LinearLayout,可以给每个控件加一层间隔线

 

<android.support.v7.widget.LinearLayoutCompat
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            app:divider="@drawable/abc_list_divider_mtrl_alpha"
            app:showDividers="middle"
            >

这里也可以采用appCompat里面的资源,如@drawable/abc_list_divider_mtrl_alpha,

 divider和showDividers是LinearLayoutCompat的特有属性,效果如图:

 

 

5.ListPopupWindow

private void showListPopWindows() {
        final String[]items={"条目0","条目1","条目2","条目3","条目4","条目5","条目6","条目7"};
        final ListPopupWindow listPopupWindow = new ListPopupWindow(this);
        listPopupWindow.setAdapter(new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,items));
        listPopupWindow.setAnchorView(mBtShowPup);//设置锚点
        listPopupWindow.setWidth(300);
        listPopupWindow.setHeight(500);
        listPopupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Toast.makeText(AppCompatWigetActivity.this, "点击--"+items[i], Toast.LENGTH_SHORT).show();
                listPopupWindow.dismiss();
            }
        });
        listPopupWindow.show();
    }

 

 展示效果如图:

 

 

 6.PopupMenu

 在res下面定义menu,编写item

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/action_setting" android:orderInCategory="100"  
      android:icon="@android:drawable/ic_menu_set_as" android:title="设置" ></item>
    <item android:id="@+id/action_share" android:orderInCategory="100"
      android:icon="@android:drawable/ic_menu_share" android:title="分享" ></item>
    <item android:id="@+id/action_add" android:orderInCategory="100"
      android:icon="@android:drawable/ic_menu_add" android:title="添加" ></item>
</menu>

 

private void showMenu() {
        PopupMenu popupMenu = new PopupMenu(this, mBtShowMenu, Gravity.CENTER);
        popupMenu.getMenuInflater().inflate(R.menu.main,popupMenu.getMenu());
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()){
                    case R.id.action_setting:
                        Toast.makeText(AppCompatWigetActivity.this, "点击---"+item.getTitle(), Toast.LENGTH_SHORT).show();
                        break;
                    case R.id.action_share:
                        Toast.makeText(AppCompatWigetActivity.this, "点击---"+item.getTitle(), Toast.LENGTH_SHORT).show();
                        break;
                    case R.id.action_add:
                        Toast.makeText(AppCompatWigetActivity.this, "点击---"+item.getTitle(), Toast.LENGTH_SHORT).show();
                        break;
                }
                return false;
            }
        });
        popupMenu.show();
    }

 

 效果如图所示:

 

 

 7.RecyclerView

private void initRecyclerView() {
        mList = Arrays.asList(mStrings);
        mRy.setLayoutManager(new GridLayoutManager(this,3));
        mAdapter = new MainRecyclerAdapter(mList);
        mRy.setAdapter(mAdapter);
        mAdapter.setItemClickListener(new MainRecyclerAdapter.ItemClickListener() {
            @Override
            public void click(View view, int position, String text) {
                Toast.makeText(MainActivity.this, "点击--"+text, Toast.LENGTH_SHORT).show();
                goActivity(position);
            }
        });
    }
