前言:
SDK更新的历史上几个特别重要的版本14（4.0）、19（4.4）、21（5.0）,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 <ProgressBar2 ?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); ???????????} ???????}); ???}Metail Design各个控件(二)
