基本的にすべてのフォーム コンポーネントを含むアクティビティがあります。以前は、組み込みのカメラのアプリを使用して画像をクリックして保存する機能を追加するまで、EditText ボックスにいくつかの基本的なテキスト フィルタリングが適用されていました。
現在、「写真を撮る」部分は正常に機能していますが、最初の 2 つの Edittext ボックスに提供された入力はフィルタリングされていません。
ここで何か不足していますか？
また、アクティビティの onCreate メソッドは setonclick リスナーを 1 つしか持つことができないようなものですか?
ありがとう..
これが私の活動のコードです:

private EditText outletEdit;
private EditText ownerEdit;
private EditText phone1Edit;
private EditText phone2Edit;
private EditText phone3Edit;
private EditText phone4Edit;
private EditText cityEdit;
private EditText stateEdit;
private EditText MrktAreaEdit;
private RadioButton ownVehYes;
private RadioButton ownVehNo;
private static int TAKE_PICTURE = 1;
private Uri outputFileUri;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ques1);
Button outletPic = (Button) findViewById(R.id.Button01_outletpic);
outletPic.setOnClickListener(new View.OnClickListener() {
public void onClick(View v2) {
TakePhoto();
}
});
//CUSTOM INPUTFILTER HERE 2.0

@Override

if (source instanceof SpannableStringBuilder) {
SpannableStringBuilder sourceAsSpannableBuilder = (SpannableStringBuilder)source;
for (int i = end - 1; i >= start; i--) {
char currentChar = source.charAt(i);
if (!Character.isLetter(currentChar) && !Character.isSpaceChar(currentChar)) {
sourceAsSpannableBuilder.delete(i, i+1);
}
}
return source;
} else {
StringBuilder filteredStringBuilder = new StringBuilder();
for (int i = 0; i < end; i++) {
char currentChar = source.charAt(i);
if (Character.isLetter(currentChar) || Character.isSpaceChar(currentChar)) {
filteredStringBuilder.append(currentChar);
}
}
return filteredStringBuilder.toString();
}
}
