android editText 软键盘enter键图标的设置

转自：http://blog.youkuaiyun.com/howlaa/article/details/36895021?utm_source=tuicool&utm_medium=referral

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_NONE
actionGo 去往，对应常量EditorInfo.IME_ACTION_GO
actionSearch 搜索，对应常量EditorInfo.IME_ACTION_SEARCH   
actionSend 发送，对应常量EditorInfo.IME_ACTION_SEND
actionNext 下一个，对应常量EditorInfo.IME_ACTION_NEXT 
actionDone 完成，对应常量EditorInfo.IME_ACTION_DONE

[java]  view plain  copy

 

1. <EditText   
2.         android:layout_marginTop="10dp"  
3.         android:layout_width="match_parent"  
4.         android:layout_height="wrap_content"  
5.         android:hint="输入单位"  
6.         android:layout_marginLeft="10dp"  
7.         android:layout_marginRight="10dp"  
8.         android:singleLine="true"   
9.         android:imeOptions="actionSearch"  
10.         />  

我发现必须加android:singleLine="true" 才行

对于事件捕捉：

[java]  view plain  copy

 

1. companySearchET.setOnEditorActionListener(new TextView.OnEditorActionListener() {    
2.            public boolean onEditorAction(TextView v, int actionId,      
3.                    KeyEvent event)  {      
4.                final String  searchStr = companySearchET.getText().toString().trim();  
5.                if (actionId==EditorInfo.IME_ACTION_SEARCH    
6.                     ||(event!=null&&event.getKeyCode()== KeyEvent.KEYCODE_ENTER)) {      
7.                 //do something;    
8.                    if(searchStr == null || "".equals(searchStr)){  
9.                         Toast.makeText(CompanyChangeActivity.this, "请输入单位关键字", Toast.LENGTH_SHORT).show();  
10.                         Log.e("这里", "这里");  
11.                         return true;  
12.                     }else{  
13.                     }  
14.                 return true;    
15.                }      
16.                return false;      
17.            }      
18.        });
