我正在尝试在EditText
ActivityResult
上添加文字,但它不起作用。这就是我所做的:
private View GetNumber() {
LayoutInflater inflater = LayoutInflater.from(getBaseContext());
viewNumber = inflater.inflate(R.layout.stepper_layout, null, false);
Number_Edittext = (AppCompatEditText) viewNumber.findViewById(R.id.Pic_Edittext_Number);
RelativeLayout NumberPickerLayout = (RelativeLayout) viewNumber.findViewById(R.id.NumberPickerLayout);
RelativeLayout Pic_Number = (RelativeLayout) viewNumber.findViewById(R.id.Pic_Number);
Button numberNext = (Button) viewNumber.findViewById(R.id.numberNext);
NumberPickerLayout.setVisibility(View.VISIBLE);
Pic_Number.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, CONTACT_PICKER_RESULT);
}
});
numberNext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
num = Number_Edittext.getText().toString();
if (TextUtils.isEmpty(num)) {
verticalStepperForm.setActiveStepAsUncompleted("Please Enter or select a number");
} else {
checkNumber(num);
}
}
});
return viewNumber;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == CONTACT_PICKER_RESULT) {
Cursor cursor = null;
Uri uri = data.getData();
//Query the content uri
cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
phoneNo = cursor.getString(phoneIndex);
Number_Edittext.setText(phoneNo);
}
}
答案 0 :(得分:0)
试试这个..
公共类MainActivity扩展了AppCompatActivity {
private static final int CONTACT_PICKER_RESULT = 100;
// Create the variable
TextView mTextView;
Button pickContactBtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
// find the text view id here
mTextView = (TextView) findViewById(R.id.textView1);
// do your work here
mTextView.setText("Hello World!");
pickContactBtn= (Button) findViewById(R.id.pickContactBtn);
pickContactBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, CONTACT_PICKER_RESULT);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == CONTACT_PICKER_RESULT) {
Cursor cursor = null;
Uri uri = data.getData();
//Query the content uri
cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String phoneNo = cursor.getString(phoneIndex);
mTextView.setText(phoneNo);
}
}
}
