Question

我在设备上展示了界面。

我在向模拟器演示时发现了设备大小及其大小的差异。

我该怎么办？尺码适合大多数设备？看看两张图片之间的区别：

    }
     public TextView makeTableRowWithText(String text, int widthInPercentOfScreenWidth, int fixedHeightInPixels) {
            int screenWidth = getResources().getDisplayMetrics().widthPixels;
            recyclableTextView = new TextView(this);
            recyclableTextView.setText(text);
            recyclableTextView.setTextColor(Color.BLACK);
            recyclableTextView.setTextSize(20);
            recyclableTextView.setWidth(widthInPercentOfScreenWidth * screenWidth / 100);
            recyclableTextView.setHeight(fixedHeightInPixels);
            return recyclableTextView;
        }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        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();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

和XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="right"
    android:id="@+id/fillable_area">
    <TableLayout
      android:gravity="right"
      android:id="@+id/table_header"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"/>
    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

  <LinearLayout android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

         <HorizontalScrollView
         android:id="@+id/scroller"
         android:layout_width="0dp"
         android:layout_weight="1"
         android:layout_height="wrap_content">

             <TableLayout
                android:id="@+id/scrollable_part"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"/>
         </HorizontalScrollView>

         <TableLayout
                android:id="@+id/scrollable_part2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>
    </LinearLayout>

    </ScrollView>

</LinearLayout>

你可以分配重量而不是重力吗？我不确定。也许你可以做match_parent而不是fill_parent？我不确定，我仍然是一个制作应用程序和东西的菜鸟。请投票。
