android editText 软键盘enter键图标的设置

EditText通过设置android:imeOptions来改变默认的”文本或者样式。这里举几个常用的常量值：actionUnspecified 未指定，对应常量EditorInfo.IME_ACTION_UNSPECIFIED. actionNone 没有动作,对应常量EditorInfo.IME_ACTION_NONEactionGo 去往，对应常量EditorInfo.IME_ACTION_GOactionSearch 搜索，对应常量EditorInfo.IME_ACTION_SEARCH actionSend 发送，对应常量EditorInfo.IME_ACTION_SENDactionNext 下一个，对应常量EditorInfo.IME_ACTION_NEXT actionDone 完成，对应常量EditorInfo.IME_ACTION_DONE

<EditText         android:layout_marginTop="10dp"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="输入单位"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"		android:singleLine="true"         android:imeOptions="actionSearch"        />

我发现必须加android:singleLine="true" 才行对于事件捕捉：

	companySearchET.setOnEditorActionListener(new TextView.OnEditorActionListener() {  		       public boolean onEditorAction(TextView v, int actionId,    		               KeyEvent event)  {    		    	   final String  searchStr = companySearchET.getText().toString().trim();		           if (actionId==EditorInfo.IME_ACTION_SEARCH  		                ||(event!=null&&event.getKeyCode()== KeyEvent.KEYCODE_ENTER)) {    		            //do something;  		        	   if(searchStr == null || "".equals(searchStr)){							Toast.makeText(CompanyChangeActivity.this, "请输入单位关键字", Toast.LENGTH_SHORT).show();							Log.e("这里", "这里");							return true;						}else{						}		            return true;  		           }    		           return false;    		       }    		   });
