從按鈕點擊EditText清除焦點 - Android

-1

總共有5個EditText。
我正在調用一個方法setOnFocusChangeListener的EditText，例如txt_location。
雖然我點擊保存並繼續按鈕我正在驗證所有的EditTexts。
當我點擊保存並繼續按鈕txt_location - EditText自動獲得我不想要的焦點。

txt_location.clearFocus（）
other_edittext.requestFocus（）

我的代碼如下圖所示。

AddAddressFragment.java

以下方法在onActivityCreated方法。

txt_location.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View view, boolean hasFocus) { 
      if (hasFocus) { 

       txt_location.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 
         findPlace(); 
        } 
       }); 
       findPlace(); 
      } 
     } 
    }); 

layoutFooter.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if(isvalidateFields()){ 
       // Code after validating all EditTexts 
      } 
     } 
    });

下面的方法在onActivityCreated方法之外。

private boolean isvalidateFields() { 
    boolean result = true; 
    if (!ValidationUtils.hasText(txtCity, cityTxt, "City Required")) { 
     result = false; 
    } 
    if (!ValidationUtils.hasText(txt_location, location_txt, "Location Required")) { 
     result = false; 
    } 
    if (!ValidationUtils.hasText(txtPincode, pincodeTxt, "Pincode Required")) 
     result = false; 
    if (!ValidationUtils.hasText(txtDoorName, doorNumberTxt, "Address line 1 Required")) { 
     result = false; 
    } 
    if (!ValidationUtils.hasText(txtApartmentName, apartmentTxt, "Address line 2 Required")) { 
     result = false; 
    } 
    return result; 
}

我找到替代解決方案ZeroOne的答案沒有爲我工作。我刪除了setOnFocusChangeListener並將setOnEditorActionListener放在EditText上，該EditText就在txt_location - EditText之前。我把setOnTouchListener到txt_location - EditText。

setOnEditorActionListener - 它會在您點擊鍵盤上的NEXT LINE按鈕時調用。

完全更改的代碼如下所示。

EditTextJustBefore_txt_location_EditText.setOnEditorActionListener(new TextView.OnEditorActionListener() { 
     @Override 
     public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { 
      if (actionId == EditorInfo.IME_ACTION_NEXT) { 
       findPlace(); 
      } 
      return true; 
     } 
    }); 

    txt_location.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      if (event.getAction() == MotionEvent.ACTION_DOWN) { 
       findPlace(); 
      } 
      return false; 
     } 
    });

給ID是否與父佈局例如：LinearLayout中，然後linearLayout.requestFocus()

，並把這個

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/linearlayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:descendantFocusability="beforeDescendants" <-- add this 
    android:focusableInTouchMode="true" <-- add this 
> 

..... 

</LinearLayout>

如何把'linearLayout.requestFocus（）'？我已經在'layoutFooter.setOnClickListener（新視圖。OnClickListener（）{@Override 公共無效的onClick（視圖v）{ 如果（isvalidateFields（））{ }其他{ ll_address_frag.requestFocus（）; } } }）;' 但它不工作@ ZeroOne –
