数字键盘二 关于获取不到光标

关于如何能获取到光标的时候 又不弹出系统软键盘java

 

首先android

2.自定义EditText输入框控件ide

这时 你会发现,光标是出来了 可是输入文字,光标永远在前面,怎么办,解决思路,监听文字文本内容变化监听方法,在afterTextChanged文字输入完后,把光标移到最后.setSelection(Edittext,Edittext.length());动画

  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.会实现效果,可是会致使光标也没法显示,若是想显示光标,你就须要定义一个方法,在方法内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,初次进入隐藏软键盘(多种方式)this

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

2,点击EditText获取焦点,但不弹出软键盘.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();
   } 
}
