機器人屏幕我向下滾動上的每個輸入到EDITTEXT插入

Question

我有以下佈局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/rootLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@color/blue_bg" > 

    <ScrollView 
     android:id="@+id/scrollView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fillViewport="true" > 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:gravity="center_horizontal" 
       android:orientation="vertical" > 


.... 
       <View 
       android:layout_width="match_parent" 
       android:layout_height="0dp" 
       android:layout_weight="0.3" /> 

      <ImageView 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_marginTop="20dp" 
       android:src="@drawable/signup_illu_verificationcode" /> 

      <View 
       android:layout_width="match_parent" 
       android:layout_height="20dp" 
       android:layout_weight="0.0" /> 

      <LinearLayout 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:layout_marginBottom="5dp" 
       android:background="@android:color/white" 
       android:padding="5dp" 
       android:paddingLeft="25dp" 
       android:paddingRight="25dp" > 

       <LinearLayout 
        android:id="@+id/inputBox" 
        android:layout_width="match_parent" 
        android:layout_height="50dp" 
        android:layout_gravity="center" 
        android:layout_marginLeft="15dp" 
        android:layout_marginRight="15dp" 
        android:background="@drawable/input_box_idle" 
        android:gravity="center" 
        android:orientation="horizontal" > 

        <LinearLayout 
         android:layout_width="wrap_content" 
         android:layout_height="wrap_content" > 

         <EditText 
          android:id="@+id/verificationCodeEditText" 
          style="@style/textOnBg" 
          android:layout_width="wrap_content" 
          android:layout_height="wrap_content" 
          android:background="@android:color/transparent" 
          android:hint="- - - - -" 
          android:inputType="number" 
          android:textColor="#516063" 
          android:textColorHint="#b4c8cf" 
          android:textSize="25dp" > 
         </EditText> 
        </LinearLayout> 
       </LinearLayout> 
      </LinearLayout> 

      <View 
       android:layout_width="match_parent" 
       android:layout_height="0dp" 
       android:layout_weight="0.7" /> 

      ... 

     </LinearLayout> 
    </ScrollView> 

</RelativeLayout> 

和下面的代碼

其中假設檢測softkeboard開口和滾動視圖有點向下（一次）

public class PhoneVerifyYourNumbersActivity extends Activity { 

     private String mDisplayOptions[] = new String[3]; 
     private LinearLayout mInputBox; 
     private LinearLayout mContinueButton; 
     private TextView mVerifyByPhoneCallText; 

     private ScrollView mScrollView; 

     private EditText mVerificationCodeEditText; 
     private String mHash = null; 


     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.phone_verify_your_numbers); 

      mHash = getIntent().getStringExtra("Hash"); 

      initMembers(); 
      setOnClickListeners(); 
      initFieldsTexts(); 
      setKeyboardVisibilityListener(); 

     } 

.. 

     private void setKeyboardVisibilityListener() { 
      final View root = findViewById(R.id.rootLayout); 

      root.getViewTreeObserver().addOnGlobalLayoutListener(
        new OnGlobalLayoutListener() { 

         @Override 
         public void onGlobalLayout() { 
          // TODO Auto-generated method stub 

          int heightDiff = root.getRootView().getHeight() 
            - root.getHeight(); 
          if (heightDiff > 100) { // more than 100 pixels is 
                // probably a keyboard 
           // keyboard is shown 
           mInputBox 
             .setBackgroundResource(R.drawable.input_box_active); 
           //mScrollView.scrollTo(0, mScrollView.getBottom()); 
           mScrollView.scrollBy(0, +20); 
          } else { 
           // keyboard is not shown 
           mInputBox 
             .setBackgroundResource(R.drawable.input_box_idle); 
          } 
         } 
        }); 
     } 
} 

} 

我的清單：

<activity 
    android:name=".phone.PhoneVerifyYourNumbersActivity" 
    android:theme="@android:style/Theme.NoTitleBar" 
    android:windowSoftInputMode="stateHidden|adjustResize" /> 

一個奇怪的行爲是，每當用戶向EditText插入輸入時，滾動會以1-2dps的速度向下移動。什麼會導致這種情況？

我想這mScrollView.scrollBy(0, +20);發生多次

但我怎麼可以讓它發生一次？

（除了添加布爾標誌isMovedAlready以外的任何聰明的想法）？

Answer 1

mScrollView.scrollBy()滾動px（像素）不是dp。你可能首先要計算dp到px。
但我想你想要不同的東西。是這樣的：

View v = findViewById(R.id.verificationCodeEditText); 
mScrollView.scrollTo(0, v.getBottom()+10);//or similar 

Answer 2

// try to add one properties on AndroidManifest.xml Activity declaration like below. 
**AndroidManifest.xml** 
<activity 
    android:name="PhoneVerifyYourNumbersActivity" 
    android:windowSoftInputMode="stateHidden|adjustPan"> 
</activity>
