我的活动基本上都包含所有表单组件。 以前它只是在EditText框上应用了一些基本的文本过滤，这些工作正常，直到我添加了一个功能来点击并使用内置相机的应用程序保存图片。
现在，“拍照”部分工作正常，但前两个Edittext框中提供的输入未被过滤。
我在这里遗漏了什么吗？
此外，是否一个活动的onCreate方法只能有一个setonclick监听器？
谢谢..
这是我的活动的代码：
public class Ques1 extends Activity {
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
InputFilter filter = new InputFilter() {
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
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();
}
}
};

// LENGTH INPUTFILTERS HERE

FilterArray[0] = new InputFilter.LengthFilter(25);
this.outletEdit.setFilters(FilterArray);
this.ownerEdit.setFilters(FilterArray);
