數字鍵盤二 關於獲取不到光標

關於如何能獲取到光標的時候 又不彈出系統軟鍵盤java

 

首先android

2.自定義EditText輸入框控件ide

這時 你會發現,光標是出來了 可是輸入文字,光標永遠在前面,怎麼辦,解決思路,監聽文字文本內容變化監聽方法,在afterTextChanged文字輸入完後,把光標移到最後.setSelection(Edittext,Edittext.length());動畫

  1. Edittext.addTextChangedListener(watcher);  
  2. private TextWatcher watcher = new TextWatcher() {  
  3. @Override  
  4. public void onTextChanged(CharSequence s, int start, int before,  
  5. int count) {  
  6. }  
  7. @Override  
  8. public void beforeTextChanged(CharSequence s, int start, int count,  
  9. int after) {  
  10. }  
  11. @Override  
  12. public void afterTextChanged(Editable s) {  
  13. Edittext.setSelection(Edittext,Edittext.length());  
  14. }  
  15. };

1.會實現效果,可是會致使光標也沒法顯示,若是想顯示光標,你就須要定義一個方法,在方法內setInputType(禁止)ui

package com.hatai.smartlokey.utils.edietext;

import android.text.InputType;
import android.widget.EditText;

import java.lang.reflect.Method;

/**
 * Created by administrato on 2017-11-03.
 */

public class ShowEdietext
{
    public static void disableShowInput(EditText editText){
        if (android.os.Build.VERSION.SDK_INT <= 10){
            editText.setInputType(InputType.TYPE_NULL);
        }else {
            Class<EditText> cls = EditText.class;
            Method method;
            try {
                method = cls.getMethod("setShowSoftInputOnFocus",boolean.class);
                method.setAccessible(true);
                method.invoke(editText,false);
            }catch (Exception e) {//TODO: handle exception
            }
            try {
                method = cls.getMethod("setSoftInputShownOnFocus",boolean.class);
                method.setAccessible(true);
                method.invoke(editText,false);
            }catch (Exception e) {//TODO: handle exception
            } } }
}
et_qujian_phone_send.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
    @Override
    public void onFocusChange(View v, boolean hasFocus)
    {
        disableShowInput(et_qujian_phone_send);
        numPan.bindEditText(et_qujian_phone_send);
    }
});

 

 

1,初次進入隱藏軟鍵盤(多種方式)this

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

2,點擊EditText獲取焦點,但不彈出軟鍵盤.net

public static void setDontShowSoftInputWhenFocused(EditText editText) {
   try {
    Method setShowSoftInputOnFocus = editText.getClass().getMethod("setShowSoftInputOnFocus", boolean.class);
    setShowSoftInputOnFocus.setAccessible(true);
    setShowSoftInputOnFocus.invoke(editText, false);
   } catch (Exception e) {
    e.printStackTrace();
   } 
}
