我有9个edittext我的问题是当你在edittext中输入一个数字时我不能在其他8个edittext中输入另一个数字例如，如果我在editext中输入5，如果我想在8中输入另外5个edittext restants不会显示任何内容，将显示错误消息。

您可以将编辑文本中的文本存储到数组中。在每次文本更改时，您都可以检查它是否存在冲突。如果是，请举杯祝酒。相应地更新textInputs字符串。不确定代码是否有效，但希望你能得到这个想法。
声明一个检查数组
String[] textInputs = new String[9];
使用其他输入检查输入
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;
}
将checkTextValid(s.toString());添加到每个onTextChanged（）。
将updateInputs(0,e.toString());添加到每个afterTextChanged（）。

使用此
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);
}
});
}
}
