Question

我需要使用ListView重新创建一个选项菜单。我创建了2个布局，一个用于＆＃34;部分的标题＆＃34;和一个项目本身。

标题

<TextView
    android:id="@+id/headerTitle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Title"
    android:textColor="@android:color/holo_green_light" />

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@android:color/holo_green_light" />

设置活动

<ListView
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:id="@+id/optionList" />

我需要设置只有标题不会有OnClickListener。

活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.context = this;
    setContentView(R.layout.settings_layout);
    setupActionBar();
    this.optionsList = (ListView)findViewById(R.id.optionList);
    this.optionsList.setHeaderDividersEnabled(false);
    this.options = new ArrayList<>();
    this.options.add(new Option("Generali", "", OptionTypes.HEADER));
    this.options.add(new Option("Cartella download", parseDirectory(getSharedPreferences(MainActivity.SHARED_PREFS_NAME, MODE_PRIVATE)
            .getString("DOWNLOADDIR",
            Environment.getExternalStorageDirectory()
                    + "/ItaSAMobileSubs")), OptionTypes.NORMAL));
    this.optionsList.getChildAt(0).setOnClickListener(null);
    OptionMenuAdapter optionMenuAdapter = new OptionMenuAdapter(this, this.options);
    this.optionsList.setAdapter(optionMenuAdapter);
    this.optionsList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            switch (position){
                case 0:

                    Toast.makeText(getApplicationContext(), "Titolo", Toast.LENGTH_LONG).show();
                    break;
                case 1:
                    mDirectoryTextView = (TextView)view.findViewById(R.id.optionDescription);
                    Intent directoryIntent = new Intent(context, DirectoryChooserActivity.class);
                    directoryIntent.putExtra(DirectoryChooserActivity.EXTRA_NEW_DIR_NAME,
                            "ItaSAMobileSubs");
                    startActivityForResult(directoryIntent, REQUEST_DIRECTORY);
                    break;
            }
        }
    });
    /*mDirectoryTextView = (TextView) findViewById(R.id.settingDescr);
    mDirectoryTextView.setText(parseDirectory(getSharedPreferences(MainActivity.SHARED_PREFS_NAME, MODE_PRIVATE).getString("DOWNLOADDIR",
            Environment.getExternalStorageDirectory()
                    + "/ItaSAMobileSubs")));
    Button directoryButton = (Button) findViewById(R.id.buttonDirectory);
    directoryButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


        }
    });*/
}

private void setupActionBar() {

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setBackgroundDrawable(
            getResources().getDrawable(R.drawable.banner));
    getActionBar().setDisplayShowTitleEnabled(false);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_DIRECTORY) {
        Log.i("Prova", String.format("Return from DirChooser with result %d",
                resultCode));

        if (resultCode == DirectoryChooserActivity.RESULT_CODE_DIR_SELECTED) {
            mDirectoryTextView
                    .setText(parseDirectory(data
                            .getStringExtra(DirectoryChooserActivity.RESULT_SELECTED_DIR)));
            SharedPreferences.Editor editor = getSharedPreferences(MainActivity.SHARED_PREFS_NAME, MODE_PRIVATE).edit();
            editor.putBoolean("CHANGED", true);
            editor.putString("DOWNLOADDIR", data.getStringExtra(DirectoryChooserActivity.RESULT_SELECTED_DIR));
            editor.commit();
            Log.i("Cambiata", "" + getSharedPreferences(MainActivity.SHARED_PREFS_NAME, MODE_PRIVATE).getBoolean("CHANGED", false));
            Log.i("Directory", getSharedPreferences(MainActivity.SHARED_PREFS_NAME, MODE_PRIVATE).getString("DOWNLOADDIR", "-"));
        }
    }
}

private String parseDirectory(String path) {
    try {
        return path.replace(Environment.getExternalStorageDirectory().getCanonicalPath(), "");
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

我该怎么做？

Answer 1

对于将来的用户，覆盖适配器的isEnabled()方法可以解决问题。

@Override
public boolean isEnabled(int position) {

    if(position == 0){
       return false; // disable click on first item
    }

    return true;
}

Answer 2

在第二个布局上设置OnClickListener（使用getView()方法）并从OnItemClickListener移除ListView。

使ListView项不可单击
