即使EditText不可編輯，EditText光標仍可見

Question

我需要在EditText中引入數據，但我想使用虛擬鍵盤，而不是Android鍵盤。如果我使用setKeyListener(null)，即使在使用setCursorVisible(true)之後，光標仍不可見。

是否有可能使EditText即使不可編輯光標是可見的？

編輯2： 我發現了一個局部的方法來做到這一點，但是當我錄音兩倍的EditText上它不工作。

我對EditText做了setOnClickListner()和setOnLongClickListner()方法。在這種方法中，我隱藏窗口的軟輸入，也使用setTextIsSelectable(false)。我唯一的問題是，當我雙擊EditText軟輸入鍵盤顯示，我不知道如何隱藏它，我試圖在清單中使用android:windowSoftInputMode="stateAlwaysHidden"，但它也不起作用。

下面是我用在這一刻我的基地轉換計算器代碼。

public class MainActivity extends AppCompatActivity { 

EditText number; 
EditText base; 
boolean baseB = false; 
String numberS = "0"; 
String baseS = "10"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(activity_main); 


    //make the EditText for number and base not editable 
    number = (EditText) findViewById(R.id.number); 
    number.setKeyListener(null); 
    base = (EditText) findViewById(R.id.base); 
    base.setKeyListener(null); 

    //... more code here (changing fonts for each EditText and changing status bar color 

} 

// I have a function for each button all are the same 

public void onClickBaseChange(View v) { 
    if (baseB) { 
     baseB = false; 
     // i use toasts at this moment to know when i'm on number or base field 
     Toast.makeText(this, "Number", Toast.LENGTH_SHORT).show(); 
    } else { 
     baseB = true; 
     Toast.makeText(this, "Base", Toast.LENGTH_SHORT).show(); 
    } 
} 

public void onClickB0(View v) { 
    if (numberS.length() > 0 && !numberS.equals("0") && !baseB) { 
     numberS += "0"; 
     number = (EditText) findViewById(R.id.number); 
     number.setText(numberS, TextView.BufferType.EDITABLE); 
     number.setSelection(numberS.length()); 
    } else { 
     if (Integer.valueOf(baseS) >= 1) { 
      baseS += "0"; 
      base = (EditText) findViewById(R.id.base); 
      base.setText(baseS, TextView.BufferType.EDITABLE); 
     } 
    } 
} 

public void onClickB1(View v) { 
    if (numberS.equals("0")) { 
     numberS = "1"; 
    } else { 
     numberS += "1"; 
    } 
    number = (EditText) findViewById(R.id.number); 
    number.setText(numberS, TextView.BufferType.EDITABLE); 
    number.requestFocus(); 
    number.setSelection(numberS.length()); 
} 

和XML是這樣的：

<android.widget.RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="fill_parent" 
android:background="@color/colorBackground"

    <Button

    <!-- from this point on is the same, there are 5 LinearLayouts which 
    represents the 5 rows of button of the num pad -->  

Answer 1

您可以使用edittext.setselection（0）

或

也許你可以要求使用對焦requestFocus（）方法

Answer 2

使用此代碼可以實現這一點，

雖然制定我把基準從本地Dialpad代碼

在你的XML，你可以給這個樣子，

<[package name].KeypadlessKeypad 
     android:id="@+id/dialnumbertv" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:background="#00000000" 
     android:cursorVisible="false" 
     android:ellipsize="start" 
     android:gravity="center" 
     android:inputType="phone" 
     android:singleLine="true" 
     android:textIsSelectable="true" 
     android:textSize="30sp" 
     android:textStyle="italic" 
     android:visibility="visible"/> 

而在你的片段可以實現像這個，

public void onViewCreated(final View view, Bundle savedInstanceState) { 
     super.onViewCreated(view, savedInstanceState); 

     mDialNumbertv = view.findViewById(R.id.dialnumbertv); 

     mDialNumbertv.setCursorVisible(false); 

     mDialNumbertv.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if (!isDigitsEmpty()) { 
        mDialNumbertv.setCursorVisible(true); 
       } 
      } 
     }); 

     mDialNumbertv.addTextChangedListener(new TextWatcher() { 
      @Override 
      public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

      } 

      @Override 
      public void onTextChanged(CharSequence s, int start, int before, int count) { 

      } 

      @Override 
      public void afterTextChanged(Editable s) { 
       if (isDigitsEmpty()) { 
        mDialNumbertv.setCursorVisible(false); 
       } 
//    updateDeleteButton(); 
      } 
     }); 

     mDialNumbertv.setOnLongClickListener(new View.OnLongClickListener() { 
      @Override 
      public boolean onLongClick(View v) { 
       // Ref https://android.googlesource.com/platform/packages/apps/Contacts/+/39948dc7e34dc2041b801058dada28fedb80c388/src/com/android/contacts/dialpad/DialpadFragment.java 
       // Right now EditText does not show the "paste" option when cursor is not visible. 
       // To show that, make the cursor visible, and return false, letting the EditText 
       // show the option by itself. 
       mDialNumbertv.setCursorVisible(true); 
       return false; 
      } 
     }); 

     mDialNumbertv.setOnEditTextActionListener(
       new KeypadlessKeypad.OnEditTextActionListener() { 
        @Override 
        public void onPaste() { 
         // If some content pasted on mDialNumbertv 
         // we need to run some search on Contact and Price 

         String mobileNumber = mDialNumbertv.getText().toString(); 

         if (TextUtils.isEmpty(mobileNumber)) { 
          return; 
         } 

//      updateContactName(mobileNumber); 
        } 
       }); 

    } 

    private KeypadlessKeypad mDialNumbertv; 

    private boolean isDigitsEmpty() { 
     return mDialNumbertv.length() == 0; 
    } 

    private void setClickedDigit(final String digitToSet) { 
     if (!TextUtils.isEmpty(digitToSet)) { 

      char digit = digitToSet.charAt(0); 

      String mobileNumber = mDialNumbertv.getText() + digitToSet; 
      mDialNumbertv.getText().insert(mDialNumbertv.getSelectionStart(), digitToSet); 

      // If the cursor is at the end of the text we hide it. 
      final int length = mDialNumbertv.length(); 
      if (length == mDialNumbertv.getSelectionStart() && length == mDialNumbertv.getSelectionEnd()) { 
       mDialNumbertv.setCursorVisible(false); 
      } 
     } 
    }
