即使只允许横向,getHeight()也会给出纵向布局的值

编辑: 我刚刚发现XML导致了这个错误。当我删除" selectiontable" (drawroom使用android:layout_toRightOf =" @ + id / selectiontable")我为drawroom得到了正确的值。我设法通过在LinearLayout而不是RelativeLayout中放置selecionable和drawroom来修复它,并对XML进行了一些更改。

我有一个奇怪的问题。在另一个类中,我的代码几乎相同,并且在那里工作得很好,但是在这个类中,getHeight和getWidth的值总是错误的,并且看起来像是纵向布局的值,即使手机处于横向模式并且我在清单文件中声明了它(android:screenOrientation =" sensorLandscape")。我在创建布局后捕获它们时得到正确的值(在按下按钮后测试它以捕获它们)。这真的很奇怪,因为它的工作方式几乎与我的其他课程完全一样。 这是代码:

public class SortMaterialActivity extends AppCompatActivity
{
private LinearLayout drawroom;
...

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sort_material);

        drawroom                = (LinearLayout)findViewById(R.id.drawroom);
...
drawroom.post(new Runnable() {
            @Override
            public void run() {
                createCanvas();
                calcDensity();
                createMaterial();
            }
        });
}

private void createCanvas()
    {
        canvasWidth = drawroom.getWidth(); //wrong values here
        canvasHeight = drawroom.getHeight();
        storageroomHeight = storageroom.getHeight();

        Bitmap bitmap = Bitmap.createBitmap(canvasWidth, canvasHeight, Bitmap.Config.ARGB_8888);
        canvas = new Canvas(bitmap);
        canvasFrame.setImageBitmap(bitmap);
    }

这是XML:
