Apply the Material Theme 运用材料主题

<span class="com"><!-- res/values/styles.xml --></span><span class="pln" style="color: rgb(0, 0, 0);"></span><span class="tag" style="color: rgb(0, 0, 136);"><resources></span><span class="pln" style="color: rgb(0, 0, 0);">  </span><span class="com"><!-- your theme inherits from the material theme --></span><span class="pln" style="color: rgb(0, 0, 0);">  </span><span class="tag" style="color: rgb(0, 0, 136);"><style</span><span class="pln" style="color: rgb(0, 0, 0);"> </span><span class="atn" style="color: rgb(136, 34, 136);">name</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"AppTheme"</span><span class="pln" style="color: rgb(0, 0, 0);"> </span><span class="atn" style="color: rgb(136, 34, 136);">parent</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"android:Theme.Material"</span><span class="tag" style="color: rgb(0, 0, 136);">></span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="com"><!--</span><span class="pln" style="color: rgb(0, 0, 0);"> theme customizations </span><span class="com">--></span><span class="pln" style="color: rgb(0, 0, 0);">  </span><span class="tag" style="color: rgb(0, 0, 136);"></style></span><span class="pln" style="color: rgb(0, 0, 0);"></span><span class="tag" style="color: rgb(0, 0, 136);"></resources></span>

Design Your Layouts  设计你的布局

除了应用和自定义材料的主题，你的布局应符合材料的设计准则。当你设计你的布局，以下需要特别注意：

基线网格

Keylines

间距

触摸目标尺寸

布局结构

Specify Elevation in Your Views  在View中指定elevation属性

View可以投下的阴影，一个View的elevation值决定了它的阴影的大小和绘制的顺序。可以设置一个视图的elevation，在布局中使用属性：android:elevation

<span class="tag" style="color: rgb(0, 0, 136);"><TextView</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:id</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"@+id/my_textview"</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:layout_width</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"wrap_content"</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:layout_height</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"wrap_content"</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:text</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"@string/next"</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:background</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"@color/white"</span><span class="pln" style="color: rgb(0, 0, 0);">    </span><span class="atn" style="color: rgb(136, 34, 136);">android:elevation</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(136, 0, 0);">"5dp"</span><span class="pln" style="color: rgb(0, 0, 0);"> </span><span class="tag" style="color: rgb(0, 0, 136);">/></span>

新的translationz属性使您能够创建一个反映了暂时的elevation变化的动画。elevation的变化可在响应触摸手势时可能是有用的。

Customize Your Animations  自定义动画

可以自定义动画，如激活Activity的过渡动画和结束过渡动画

当你在这个Activity中启动其他的Activity时，exit transition将被激活
