Edittext.settext() 不要在 onActivityResult() 中显示文本

我正在尝试在EditTexton 中添加文本ActivityResult，但它不起作用。这是我所做的：

  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);
        }
    }

试试这个..

公共类 MainActivity 扩展 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);
    }
}

}
