1 如果Activity页面有EditText，为了不影响用户体验，我们需要在进入该页面时不弹出软键盘。如何设置呢？

在mainifest.xml文件中配置Activity时，设置这两句即可：

 android:configChanges="orientation|keyboardHidden"
 android:windowSoftInputMode="adjustUnspecified|stateHidden"

//隐藏输入法
	public  void closeSoftKeboard(EditText edit){
    	InputMethodManager inputMethodManager = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    	inputMethodManager.hideSoftInputFromWindow(edit.getWindowToken()
    	,0);
    }

edit.addTextChangedListener(new TextWatcher() {
			
			@Override
			public void onTextChanged(CharSequence s, int start, int before, int count) {
			}
			
			@Override
			public void beforeTextChanged(CharSequence s, int start, int count,
					int after) {
			}
			
			@Override
			public void afterTextChanged(Editable s) {
				if(s.toString().length()==11){
					closeSoftKeboard(edit);
				}
				
			}
		});
