在我的代码中，我的滑出菜单从左向右改变方向，而我希望它从右向左改变，这是我的主要活动：

public class LayerStack extends Activity {

// Declare
private LinearLayout slidingPanel;
private boolean isExpanded;
private DisplayMetrics metrics;
private RelativeLayout headerPanel;
private RelativeLayout menuPanel;
private int panelWidth;
private ImageView menuViewButton;
Button menu1;
Button menu2;
TextView txtpays;
FrameLayout.LayoutParams menuPanelParameters;
FrameLayout.LayoutParams slidingPanelParameters;
LinearLayout.LayoutParams headerPanelParameters;
LinearLayout.LayoutParams listViewParameters;

@Override
protected void onCreate(Bundle savedInstanceState) {

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

    // Initialize
    metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

    panelWidth = (int) ((metrics.widthPixels) * 0.75);

    headerPanel = (RelativeLayout) findViewById(R.id.header);
    headerPanelParameters = (LinearLayout.LayoutParams) headerPanel
            .getLayoutParams();
    headerPanelParameters.width = metrics.widthPixels;
    headerPanel.setLayoutParams(headerPanelParameters);

    menuPanel = (RelativeLayout) findViewById(R.id.menuPanel);
    menuPanelParameters = (FrameLayout.LayoutParams) menuPanel
            .getLayoutParams();
    menuPanelParameters.width = panelWidth;
    menuPanel.setLayoutParams(menuPanelParameters);

    slidingPanel = (LinearLayout) findViewById(R.id.slidingPanel);
    slidingPanelParameters = (FrameLayout.LayoutParams) slidingPanel
            .getLayoutParams();
    slidingPanelParameters.width = metrics.widthPixels;
    slidingPanel.setLayoutParams(slidingPanelParameters);

    // Slide the Panel

    menu1 = (Button) findViewById(R.id.menu_item_1);

    menu2 = (Button) findViewById(R.id.menu_item_2);

    menuViewButton = (ImageView) findViewById(R.id.menuViewButton);

    menuViewButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            if (!isExpanded) {
                isExpanded = true;

                // Expand
                new ExpandAnimation(slidingPanel, panelWidth,
                        Animation.RELATIVE_TO_SELF, 0.0f,
                        Animation.RELATIVE_TO_SELF, 0.75f, 0, 0.0f, 0, 0.0f);
            } else {
                isExpanded = false;

                // Collapse
                new CollapseAnimation(slidingPanel, panelWidth,
                        TranslateAnimation.RELATIVE_TO_SELF, 0.75f,
                        TranslateAnimation.RELATIVE_TO_SELF, 0.0f, 0, 0.0f,
                        0, 0.0f);

            }
        }
    });

}

}

这是我的expandAnimation类：

public class ExpandAnimation extends TranslateAnimation implements Animation.AnimationListener{

private LinearLayout slidingLayout;
int panelWidth;

public ExpandAnimation(LinearLayout layout, int width, int fromXType, float fromXValue, int toXType,
        float toXValue, int fromYType, float fromYValue, int toYType, float toYValue) {

    super(fromXType, fromXValue, toXType, toXValue, fromYType, fromYValue, toYType, toYValue);

    //Initialize
    slidingLayout = layout;
    panelWidth = width;
    setDuration(400);
    setFillAfter( false );
    setInterpolator(new AccelerateDecelerateInterpolator());
    setAnimationListener(this);
    slidingLayout.startAnimation(this);
}


public void onAnimationEnd(Animation arg0) {

    //Create margin and align left  *******************************put setting in blue lines in left side
    LayoutParams params = (LayoutParams) slidingLayout.getLayoutParams();
    params.leftMargin = panelWidth;
    params.gravity = Gravity.LEFT;     
    slidingLayout.clearAnimation();
    slidingLayout.setLayoutParams(params);
    slidingLayout.requestLayout();

}

我的折叠课程：

public class CollapseAnimation extends TranslateAnimation implements TranslateAnimation.AnimationListener{

private LinearLayout slidingLayout;
int panelWidth;

public CollapseAnimation(LinearLayout layout, int width, int fromXType, float fromXValue, int toXType,
        float toXValue, int fromYType, float fromYValue, int toYType, float toYValue) {

    super(fromXType, fromXValue, toXType, toXValue, fromYType, fromYValue, toYType, toYValue);

    //Initialize
    slidingLayout = layout;
    panelWidth = width;
    setDuration(400);
    setFillAfter( false );
    setInterpolator(new AccelerateDecelerateInterpolator());
    setAnimationListener(this);

    //Clear left and right margins
    LayoutParams params = (LayoutParams) slidingLayout.getLayoutParams();
    params.rightMargin = 0;
    params.leftMargin = 0;
    slidingLayout.setLayoutParams(params);
    slidingLayout.requestLayout();       
    slidingLayout.startAnimation(this);

}

和我的XML：
