編集テキストとエラーメッセージ

Question

私は9つのedittextを持っています私の質問は編集テキストに数字を入力するときです他の8つのedittextの残りの数字を入力できません例えばeditextに5と入力し、 8人のedittext restantsのうち5人は何も置かず、エラーメッセージが表示されます。

et1.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

     }

Answer 1

編集テキストのテキストを配列に格納することができます。すべてのテキストの変更時に、それが矛盾しているかどうかを確認することができます。はいの場合は、乾杯してください。それに応じてtextInputs文字列を更新します。コードが機能しているかどうかはわかりません

）がチェックアレイ

String[] textInputs = new String[9]; 

他の入力に入力をチェック

void checkTextValid(String input){ 
    if (input.length > 0 && ArrayUtils.contains(textInputs, input)) { 
     Toast.makeText(this, "vous ne devez utiliser ce nombre deux fois ", Toast.LENGTH_SHORT).show(); 
    } 
} 

void updateInputs(int id, String s){ 
    textInputs[id] = s; 
} 

各onTextChanged（へcheckTextValid(s.toString());を追加宣言します。

updateInputs(0,e.toString());を各afterTextChanged（）に追加します。

Answer 2

はエラーメッセージです。この

public class MainActivity extends AppCompatActivity { 


    EditText edt_1,edt_2,edt_3,edt_4,edt_5; 

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

     edt_1 = (EditText)findViewById(R.id.edt_1); 
     edt_2 = (EditText)findViewById(R.id.edt_2); 
     edt_3 = (EditText)findViewById(R.id.edt_3); 
     edt_4 = (EditText)findViewById(R.id.edt_4); 
     edt_5 = (EditText)findViewById(R.id.edt_5); 


     editTextWatcher(edt_1); 
     editTextWatcher(edt_2); 
     editTextWatcher(edt_3); 
     editTextWatcher(edt_4); 
     editTextWatcher(edt_5); 
    } 




    public void editTextWatcher(final EditText edt) { 
     edt.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) { 

       edt.removeTextChangedListener(this); 
       edt.setText(""); 
       edt.addTextChangedListener(this); 

       ArrayList<String> texts = new ArrayList<String>(); 
       texts.add(edt_1.getText().toString()); 
       texts.add(edt_2.getText().toString()); 
       texts.add(edt_3.getText().toString()); 
       texts.add(edt_4.getText().toString()); 
       texts.add(edt_5.getText().toString()); 

       for (String text : texts){ 
        if(s.toString().equals(text)){ 
         Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_SHORT).show(); 
         edt.removeTextChangedListener(this); 
         edt.setText(""); 
         edt.addTextChangedListener(this); 
         return; 
        } 
       } 

       edt.removeTextChangedListener(this); 
       edt.setText(s.toString()); 
       edt.addTextChangedListener(this); 


      } 
     }); 
    } 

}
