java - 旋转器和 Android

Question

我想获取微调器的值并将其转换为字符串来使用。

    Spinner s1 = (Spinner)findViewById(R.id.spinner1);
    s1.setOnItemSelectedListener((OnItemSelectedListener) this);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.languages, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    s1.setAdapter(adapter);

我认为这样的事情会起作用......

 private OnClickListener sendClickListener = new OnClickListener(){
    public void onClick(View arg0) {
        EditText dstName = (EditText) findViewById(R.id.destinationAddress);
        EditText dstLanguage = (EditText) findViewById(R.id.spinner1);

        String address = dstName.getText().toString();   
        String language = dstLanguage.getText().toString();

        ops.createSocketConnection(language, address);  
        Notification notification = new Notification();
        notification.vibrate = new long[] {100};
    }};

可惜事实并非如此......

我看过一些例子，但我不确定它们是否与我的问题直接相关。

提前致谢!

试试这个:

OnItemSelectedListener itemSelectedHandler = new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View v, int pos, long row) {
        String str = parent.getItemAtPosition(pos).toString();
        // Do whatever you want with the string
    }
    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // Do nothing
    }
};
//set the spinner's listener for select event

mSpinner.setOnItemSelectedListener(itemSelectedHandler);
