java - 多个编辑文本验证该字段是否包含在保存按钮中具有可见性的数据

Question

我已经阅读了很多帖子并提出了所有建议，但没有一个有效。首先将按钮的视图将其setVisibility 保存到GONE 的xml 中。

这是完整的课程：

        int objChasis = Integer.parseInt(edChasis.getText().toString().trim());
         String objColor = edColor.getText().toString().trim();
         int objKilometraje = Integer.parseInt(edKilometraje.getText().toString().trim());
         int objModelo = Integer.parseInt(edModelo.getText().toString().trim());
         String objPlaca = edPlaca.getText().toString().trim();

                    objModelo, objPrecio, objChasis, objKilometraje, objMotor, objSucursal);


                databaseReference.push().setValue(autosAdmin);
                String key = databaseReference.getKey();
                Toast.makeText(this, "save ok", Toast.LENGTH_SHORT).show();
            }

                chasis = edChasis.getText().toString().trim();
                 color = edColor.getText().toString().trim();
                kilometraje = edKilometraje.getText().toString().trim();

                        &&!color.matches("")
                        &&!kilometraje.matches("")

                    admBotonGuardar.setVisibility(View.VISIBLE);

                }

            }

            @Override
            public void afterTextChanged(Editable s) {

            }
        };

    }

当我模拟应用程序时，保存按钮消失了，但是当我填写 editText 字段时，它应该出现的按钮！但这只是没有发生！

这是更新的代码：

 public void GuardarAutomoviles() {

//        if(image!=null) {

        String objMarca = edMarca.getText().toString().trim();
        int objChasis = Integer.parseInt(edChasis.getText().toString().trim());
        String objColor = edColor.getText().toString().trim();
        int objKilometraje = Integer.parseInt(edKilometraje.getText().toString().trim());
        int objModelo = Integer.parseInt(edModelo.getText().toString().trim());
        String objPlaca = edPlaca.getText().toString().trim();
        String objMotor = edMotor.getText().toString().trim();
        int objPrecio = Integer.parseInt(edPrecio.getText().toString().trim());
        String objReferencia = edReferencia.getText().toString().trim();
        String objSucursal = edSucursal.getText().toString().trim();


        edMarca.addTextChangedListener(adminTextwatcher);
        edChasis.addTextChangedListener(adminTextwatcher);
        edColor.addTextChangedListener(adminTextwatcher);
        edKilometraje.addTextChangedListener(adminTextwatcher);
        edModelo.addTextChangedListener(adminTextwatcher);
        edPlaca.addTextChangedListener(adminTextwatcher);
        edMotor.addTextChangedListener(adminTextwatcher);
        edPrecio.addTextChangedListener(adminTextwatcher);
        edReferencia.addTextChangedListener(adminTextwatcher);
        edSucursal.addTextChangedListener(adminTextwatcher);



        if (!chasis.isEmpty()
                || !color.isEmpty()
                || !kilometraje.isEmpty()
                || !modelo.isEmpty()
                || !placa.isEmpty()
                || !motor.isEmpty()
                ||!precio.isEmpty()
                || !referencia.isEmpty()
                || !sucursal.isEmpty()) {
            admBotonGuardar.setVisibility(View.VISIBLE);
        }

        marca = edMarca.getText().toString().trim();
        chasis = edChasis.getText().toString().trim();
        color = edColor.getText().toString().trim();
        kilometraje = edKilometraje.getText().toString().trim();
        modelo = edModelo.getText().toString().trim();
        placa = edPlaca.getText().toString().trim();
        motor = edMotor.getText().toString().trim();
        precio = edPrecio.getText().toString().trim();
        referencia = edReferencia.getText().toString().trim();
        sucursal = edSucursal.getText().toString().trim();




            Automoviles autosAdmin = new Automoviles(objMarca, objPlaca, objReferencia, objColor, image,
                    objModelo, objPrecio, objChasis, objKilometraje, objMotor, objSucursal);


            databaseReference.push().setValue(autosAdmin);
            String key = databaseReference.getKey();
            Toast.makeText(this, "save ok", Toast.LENGTH_SHORT).show();
        }

您正在检查matches()哪个是错误的。您应该检查字符串对象.isEmpty()

或者你也可以使用TextUtils.isEmpty(string)
