如何在 SimpleCursorAdapter - Android 中自定义 TextViews

Question

我想在 SimpleCursorAdapter 中自定义我的文本视图，有人可以帮助我以一种不需要太多代码更改的最简单的方式来做到这一点...

下面是我的工作代码，我从一个类中获取字符串并插入到 SimpleCursorAdapter 中

代码：

public class MyListActivity extends ListActivity {
    /** Called when the activity is first created. */


    private Cursor mCursor = null;


    @SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.weeklysettings);
        getListView().addHeaderView(buildHeader(), null , false);
        Cursor mCursor = getCursorDetails();
        startManagingCursor(mCursor);

        ListAdapter adapter = new SimpleCursorAdapter(this, // Context.
                R.layout.listview, // Specify the row template
                                    // to use (here, three
                                    // columns bound to the
                                    // two retrieved cursor
                                    // rows).
                mCursor, // Pass in the cursor to bind to.
                // Array of cursor columns to bind to.
                new String[] { MyClass.EVENT,
                MyClass.CHANNEL_NAME,
                MyClass.PROGRAM_TITLE,
                MyClass.EVENTTIME },

                new int[] { R.id.event, R.id.channelname, R.id.programtitle, R.id.timestamp});
        // Bind to our new adapter.
        setListAdapter(adapter);
        //setListAdapter(new ArrayAdapter<String>(this, R.layout.listview, ynetList));

    }

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        stopManagingCursor(mCursor);
    }


    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        startManagingCursor(mCursor);
    }
    private ViewGroup buildHeader() {
        LayoutInflater infalter = getLayoutInflater();
        ViewGroup header = (ViewGroup) infalter.inflate(R.layout.listitem_header, getListView(), false);
        header.setEnabled(false);
        return(header);
      }
    @Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
         Intent intent = new Intent(this, SettingsActivity.class);
         intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
         startActivity(intent);
         finish();
         super.onBackPressed();
    }

    private Cursor getCursorDetails() {


        String sortOrder = DataExchangeFacility.TIMESTAMP
                + " COLLATE LOCALIZED DESC";

        mCursor = getApplicationContext().getContentResolver().query(
                DataExchangeFacility.CONTENT_URI_GRACE, null, null, null, sortOrder);

        return mCursor;

    }
}

试一试：

    ListAdapter adapter = new SimpleCursorAdapter(this, // Context.
            R.layout.listview, // Specify the row template
            // to use (here, three
            // columns bound to the
            // two retrieved cursor
            // rows).
            mCursor, // Pass in the cursor to bind to.
            // Array of cursor columns to bind to.
            new String[] { MyClass.EVENT,
                    MyClass.CHANNEL_NAME,
                    MyClass.PROGRAM_TITLE,
                    MyClass.EVENTTIME },

            new int[] { R.id.event, R.id.channelname, R.id.programtitle, R.id.timestamp}) {
        @Override
        public void setViewText(TextView v, String text) {
            // v is your TextView
            v.setTextColor(Color.RED);
            super.setViewText(v, text);
        }
    };
