私のコードでは、右から左に変更したいときにスライドアウトメニューの方向が左から右に変わります。これが私のメインアクティビティです:
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);
}
}
});
}
}
これは私の expandAnimation クラスです:
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();
}
私の崩壊クラス：
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);
}
そして私のXML：
