Question

我有一个活动，它有主题作为对话框。在这个活动中，有10个编辑文本。对于一个编辑框，我无法将文本设置到编辑框。

public void onCreate（Bundle savedInstanceState）{

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);     
    is_tablet=SharedVariables.sharedPrefDate.getBoolean("isTablet", false);
    if(!is_tablet){
        super.setTheme(android.R.style.Theme_Black_NoTitleBar);
    }
    //overridePendingTransition(R.anim.slide_bottom_to_top,0);
    super.onCreate(savedInstanceState);
    activity=UpdateCasePersonAddressScreen.this;
    setContentView(R.layout.update_person_address_screen);



    //allocating memory to objBLAddCasePersonScreenOperations
    objBLAddPersonAddressScreenOperations=new BLAddUpdatePersonAddressScreenOperations();
    objBLCommonOperations=new BLCommonOperations(); 
    getAllIds();


    //objPersonAddress=new clsPersonAddress();
    bundle = getIntent().getExtras();

    //code to get all objects using Bundle from previous activity
    if(bundle!=null){

        objPersonAddress = (clsPersonAddress) bundle.getParcelable("clsPersonAddress");
        System.out.println("from Extras");
        bundle=null;
    }        



    initTextFields();
    inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    /* if (inputMethodManager != null) {
        inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }*/
}
public void initTextFields(){

    updatePersonAddressTitleEditText.setText(objPersonAddress.getAddressTitle());
    updatePersonAddressMemoEditText.setText(objPersonAddress.getAddressMemo());
    updatePersonAddressNameEditText.setText(objPersonAddress.getAddressName());
    updatePersonAddressBusinessNameEditText.setText(objPersonAddress.getAddressBusinessName());
    updatePersonAddressWorkPhoneEditText.setText(objPersonAddress.getAddressWorkPhone());
    updatePersonAddressHomePhoneEditText.setText(objPersonAddress.getAddressHomePhone());
    updatePersonAddressMobilePhoneEditText.setText(objPersonAddress.getAddressMobilePhone());
    updatePersonAddressAddressLine1EditText.setText(objPersonAddress.getAddressLine1());
    updatePersonAddressAddressLine2EditText.setText(objPersonAddress.getAddressLine2());
    updatePersonAddressCityEditText.setText(objPersonAddress.getAddressCity());

    System.out.println("objPersonAddress.getAddressState()))))))))))))))))))))))))))))))))))"+objPersonAddress.getAddressState());

    updatePersonAddressStateEditText.setText(objPersonAddress.getAddressState().toString());//setText(objPersonAddress.getAddressState(), TextView.BufferType.EDITABLE);
    System.out.println("updatePersonAddressStateEditText text is now is:"+updatePersonAddressStateEditText.getText().toString()+"null check:"+updatePersonAddressStateEditText.toString());
    System.out.println("below objPersonAddress.getAddressState()))))))))))))))))))))))))))))))))))"+objPersonAddress.getAddressState());

    updatePersonAddressZipEditText.setText(objPersonAddress.getAddressZip());
    updatePersonAddressCountryEditText.setText(objPersonAddress.getAddressCountry());
}

任何人都可以在这个问题上帮助我。在Advance中感谢任何帮助。

Answer 1

EditText edit;// define it before onCreate

edit=(EditText)findViewById(R.id.edittext); //get it from xml

String value="123";
//simply use 

edit.setText(value);

Answer 2

Android原生：

String text = "Example";
EditText edtText = (EditText) findViewById(R.id.edtText);
edtText.setText(text);`

看！ EditText只接受String值，必要时转换为String。

如果是int，double，long值，请执行：

String.value(value);

例：

int i = 5;
edtText.setText(String.value(i));

Android注释：

@ViewById
EditText edtText;

设置：

@UiTread
void setText(){
    edtText.setText("Text");
}

致电：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        
    this.setText();
}

Answer 3

就这样写下来

EditText editText=(EditText)findViewById(R.id.editText1);
        editText.setText("abc");

settext在android中编辑文本
