            android:layout_width="fill_parent"
            android:stretchColumns="2"

code for filling the data to table row

 for (Forecastday forecastday : forcastDayList) {


                        View view = inflater.inflate(R.layout.weather_forcast_day_view, null);
                        TextView focast_day = (TextView) view.findViewById(R.id.focast_day);
                        TextView focast_day_temp = (TextView) view.findViewById(R.id.focast_day_temp);
                        ImageView  focast_day_skyIcon = (ImageView) view.findViewById(R.id.focast_day_skyIcon);

                        TableRow row = new TableRow(_appContext);
                        focast_day.setText(fmtDate);


                        focast_day_temp.setText(forecastday.getHigh().getCelsius() +ApplicationConstants.STRING_SPACE +ApplicationConstants.CELSIUS_DEGREES);
                        focast_day_temp.setId(count);


                        focast_day_skyIcon.setImageBitmap(forecastday.getSkyiconBitMap());


                        row.addView(view);
                        weatherforcastTable.addView(row, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                                LayoutParams.WRAP_CONTENT));
                    }

回答1:

Could you try this : stretchColumns="0,1,2" on the TableLayout

<TableLayout
        android:id="@+id/weatherforcastTable"
        android:layout_width="fill_parent"
        android:stretchColumns="0,1,2"
        android:layout_height="wrap_content"
        android:layout_below="@+id/today_temp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="34dp" >
</TableLayout>

回答2:

Did you try using "layout_gravity" instead of "gravity" on the first and last columns in the xml layout for the row? This might fix your problem by aligning forecast_day to the left of the parent table and forecast_day_skyIcon to the right.

Here's a good visualization of gravity vs. layout_gravity

This one worked for me.

<TableRow 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center">

Hope it helps.
