Android的微调错误 [英] Android Spinner Error

问题描述

您好我尽量把我的java codeA微调，但它显示了其他的if语句错误：

hello I try to put in my java Code a Spinner, but it shows in the else if statement error:

    private EditText textName;
    private EditText textContent;
    private Spinner CategorySpinner;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_text);



        configureButton1();
        configureButton2();

        textName = (EditText) findViewById(R.id.editTextName);
        textContent = (EditText) findViewById(R.id.editContent);
        CategorySpinner = (Spinner) findViewById(R.id.editCategorySpinner);



    }

    private void configureButton1() {
        Button del = (Button)findViewById(R.id.btNewText);
        del.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent myIntent = new Intent(v.getContext(), StartActivity.class);
                v.getContext().startActivity(myIntent);
            }
        });
    }

    private void configureButton2() {
        Button save = (Button) findViewById(R.id.btSave);

        save.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (textName.getText().length() == 0) {
                    textName.requestFocus();
                    return;
                } else if (textContent.getText().length() == 0) {
                    textContent.requestFocus();
                    return;
                } else if (CategorySpinner.**getText**().length() == 0) {
                    CategorySpinner.requestFocus();
                    return;
                } else {
                    //next Step: get the mood
                    Intent myIntent = new Intent(v.getContext(), Activity2.class);
                myIntent.putExtra("textName", textName.getText().toString());
                myIntent.putExtra("textContent", textContent.getText().toString());
                myIntent.putExtra("CategorySpinner", CategorySpinner.**getText()**.toString());
                v.getContext().startActivity(myIntent);
            }
                }
            }
        });
        }

它示出了在CategorySpinner.getText（）中的错误。我希望你能帮助我。 从来就尝试了很多，但没有找到一个解决方案。

it shows in the CategorySpinner.getText() an error. I hope you can help me. I´ve tried a lot, but not found a solution.

现在我已经加入了数组适配器，但它再次显示了其他-if语句错误：

Now I have add the Array Adapter, but it shows again in the else-if statement error:

    // Create an ArrayAdapter using the string array and a default spinner layout
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                R.array.category_array, android.R.layout.simple_spinner_item);
        // Specify the layout to use when the list of choices appears
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        // Apply the adapter to the spinner
        categorySpinner = (Spinner) findViewById(R.id.editCategorySpinner);

        categorySpinner.setAdapter(adapter);
        categorySpinner.setOnItemSelectedListener(this);

}

private void configureButton2() {
        Button save = (Button) findViewById(R.id.btSave);

        save.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (textName.getText().length() == 0) {
                    textName.requestFocus();
                    return;
                } else if (textContent.getText().length() == 0) {
                    textContent.requestFocus();
                    return;
                } else if (categorySpinner.**getText**().length() == 0) {
                    CategorySpinner.requestFocus();
                    return;
                } else {
                    //next Step: get the mood
                    Intent myIntent = new Intent(v.getContext(), Activity2.class);
                myIntent.putExtra("textName", textName.getText().toString());
                myIntent.putExtra("textContent", textContent.**getText**().toString());
                myIntent.putExtra("CategorySpinner", CategorySpinner.**getText()**.toString());
                v.getContext().startActivity(myIntent);
            }
                }
            }
        });
        }

@Override
    public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {

        String selected = parent.getItemAtPosition(pos).toString();

    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }

我希望你能帮助我。

I hope you can help me.
