作者:javaer / 发布于2012/3/6/ 534

在android开发中，在表单提交的场景下想获取activity上所有的控件

<div>/**</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span> * @note 获取该activity所有view</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span> * @author liuh</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span> * */</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>public List<View> getAllChildViews() {</div>
<div><span class="Apple-tab-span" style="white-space:pre">		</span>View view = this.getWindow().getDecorView();</div>
<div><span class="Apple-tab-span" style="white-space:pre">		</span>return getAllChildViews(view);</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>}
<div></div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>private List<View> getAllChildViews(View view) {</div>
<div><span class="Apple-tab-span" style="white-space:pre">		</span>List<View> allchildren = new ArrayList<View>();</div>
<div><span class="Apple-tab-span" style="white-space:pre">		</span>if (view instanceof ViewGroup) {</div>
<div><span class="Apple-tab-span" style="white-space:pre">			</span>ViewGroup vp = (ViewGroup) view;</div>
<div><span class="Apple-tab-span" style="white-space:pre">			</span>for (int i = 0; i < vp.getChildCount(); i++) {</div>
<div><span class="Apple-tab-span" style="white-space:pre">				</span>View viewchild = vp.getChildAt(i);</div>
<div><span class="Apple-tab-span" style="white-space:pre">				</span>allchildren.add(viewchild);</div>
<div><span class="Apple-tab-span" style="white-space:pre">				</span>allchildren.addAll(getAllChildViews(viewchild));</div>
<div><span class="Apple-tab-span" style="white-space:pre">			</span>}
<div><span class="Apple-tab-span" style="white-space:pre">		</span>}
<div><span class="Apple-tab-span" style="white-space:pre">		</span>return allchildren;</div>
<div><span class="Apple-tab-span" style="white-space:pre">	</span>}
