Android TextView（在ListView中）单击文本本身时单击未注册的项

我制作了一个InfoscreenActivity，在我的应用程序中显示一个“设置/关于”页面（包含应用程序版本信息、许可证、联系人、设置和备份选项）。该页面上的项目是使用名为InfoscreenAdapter的自定义ArrayAdapter在ListView中生成的

下面是相关的类和xml布局文件

活动信息屏幕活动：

public class InfoscreenActivity extends ActionBarActivity {
    private static final String TAG = "InfoscreenActivity";
    private InfoscreenItem appVersion;
    private InfoscreenItem iiLicenses;
    private InfoscreenItem contactUs = new InfoscreenItem("Contact us");
    private InfoscreenItem iiSetup = new InfoscreenItem("Launch Setup");
    private InfoscreenItem iiBackup = new InfoscreenItem("Perform Backup");

    ListView lv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        if(AppConfig.DEBUG) Log.i(TAG, "launching onCreate() ...");

        String appVersionString;

        if(AppConfig.DEBUG) Log.i(TAG, "trying to fetch the version name ...");
        try {
            appVersionString = SetupActivity.getVersionName(this);
            appVersion = new InfoscreenItem("App version", appVersionString);
        } catch (Exception e) {
            if(AppConfig.DEBUG) Log.e(TAG, e.getMessage());
        }

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_infoscreen);

        iiLicenses = new InfoscreenItem(getResources().getString(R.string.title_activity_licenses));

        // Get ListView object from xml
        lv = (ListView) findViewById(R.id.infoscreenListViewID);
        // Defined Array values to show in ListView
        InfoscreenItem[] items = new InfoscreenItem[] {appVersion, contactUs, iiLicenses, iiSetup, iiBackup};
        // Define a new InfoscreenAdapter
        InfoscreenAdapter adapter = new InfoscreenAdapter(this, items);
        // Assign adapter to ListView
        if(AppConfig.DEBUG) Log.i(TAG, "setting adapter");
        lv.setAdapter(adapter);

        // React to user clicks on item
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            public void onItemClick(AdapterView<?> parentAdapter, View view, int position,
                                    long id) {
                if(AppConfig.DEBUG) Log.i(TAG, "item " + Integer.toString(position) + " clicked.");

                // for the "Contact us" item
                if(position == 1) {
                    TextView clickedView = (TextView) view.findViewById(R.id.textView);
                    onContactClick(clickedView);
                }

                // for the "Licenses" item
                if(position == 2) {
                    TextView clickedView = (TextView) view.findViewById(R.id.textView);
                    onLicensesClick(clickedView);
                }

                // for the "Setup" item
                if (position == 3) {
                    if (AppConfig.DEBUG) Log.d(TAG, "launching Setup Activity...");
                    startActivity(new Intent(getApplication(), SetupActivity.class));
                }

                // for the "Backup" item
                if (position == 4) {
                    Intent iBackup = new Intent(getApplication(), BackupAndRestoreActivity.class);
                    iBackup.putExtra("MODE", 1);
                    startActivity(iBackup);
                }

            }
        });

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        if(AppConfig.DEBUG) Log.i(TAG, "exiting onCreate() ...");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        if(AppConfig.DEBUG) Log.i(TAG, "onCreateOptionsMenu() ...");
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_infoscreen, menu);
        if(AppConfig.DEBUG) Log.i(TAG, "exiting onCreateOptionsMenu() ...");
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        else if (id == android.R.id.home) {
            finish();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void onContactClick(View v) {
        Intent email = new Intent(Intent.ACTION_SEND);
        email.putExtra(Intent.EXTRA_EMAIL, new String[]{"contact@gmail.com"});
        email.putExtra(Intent.EXTRA_SUBJECT, "(subject)");
        email.putExtra(Intent.EXTRA_TEXT, "(message)");
        email.setType("message/rfc822");
        startActivity(Intent.createChooser(email, "Choose an Email client :"));
    }

    public void onLicensesClick(View v) {
        if(AppConfig.DEBUG) Log.i(TAG, "onLicensesClick() ...");

        startActivity(new Intent(InfoscreenActivity.this, LicensesActivity.class));
    }
}

现在，除了在“信息屏幕”的列表视图中，项目只能单击文本旁边的项目外，所有项目都按预期工作。是否有任何方法可以使整个ListView项目对单击作出反应，而不管您在何处单击该项目？xml布局模板中是否缺少某些内容？我尝试过设置android:clickable=“true”，删除它，尝试改变android:layout\u width=“wrap\u content”以匹配父对象或填充父对象（正如其他类似线程中所建议的那样，这些都是不可点击的，所以问题与我现在遇到的完全不同）在您的

item\u infoscreen\u dual\u line.xml
或
item\u infoscreen\u single\u line.xml
中（我不知道是哪一个引起了您的麻烦）为您的线性布局提供一个id。现在找到该布局并在该布局上设置OnClickListener。
简单。您已为textview添加了填充。但您希望单击整个LinearLayout项目。因此，不要将填充内容写入TextView，而是将其用于LinearLayout
好的，非常感谢您的输入。我在谷歌上做了更多的搜索，无意中发现了这个项目，并在我的Android Studio中创建了这个项目。在本例中，单击在任何地方都有效，因此我开始逐个删除xml属性以匹配示例中的xml，结果发现删除android:clickable=“true”解决了这个问题。我有点困惑（听起来有点矛盾），但它是有效的。
你的意思是在线性布局中不使用文本视图？（顺便说一句，两者都有相同的问题…）。因为现在，我将onClickListener设置为ListView本身，并在onItemClick（）中获取TextView。
