修改狀態列與導航欄顏色
阿新 • • 發佈：2018-11-20
1.修改狀態列
可進行自定義
public class StatusBarView extends View {
private Context context;
public StatusBarView(Context context) {
this(context,null);
}
public StatusBarView(Context context, AttributeSet attrs) {
super(context, attrs);
this.context=context;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(ScreenUtils.getStatusBarHeight(context), MeasureSpec.EXACTLY));
}
}<com.cy.translucentparent.StatusBarView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#33000000" />
2.工具類
a.解析度轉換工具類
public class ScreenUtils {
//獲得狀態列高度
public static int getStatusBarHeight(Context context) {
Resources resources = context.getResources();
int resourceId = resources.getIdentifier("status_bar_height", "dimen", "android");
return resources.getDimensionPixelSize(resourceId);
}
//獲得導航欄高度
public static int getNavigationBarHeight(Context context) {
Resources resources = context.getResources();
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
return resources.getDimensionPixelSize(resourceId);
}
//獲得螢幕寬度
public static int getScreenWidth(Context context) {
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager wm = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getMetrics(displayMetrics);
return displayMetrics.widthPixels;
}
//獲得螢幕高度
public static int getScreenHeight(Context context) {
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager wm = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getMetrics(displayMetrics);
return displayMetrics.heightPixels;
}
/**
* 將px值轉換為dip或dp值，保證尺寸大小不變
*
* @param pxValue
* @param scale （DisplayMetrics類中屬性density）
* @return
*/
public static int px2dp(Context context, float pxValue) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int) (pxValue / scale + 0.5f);
}
/**
* 將dip或dp值轉換為px值，保證尺寸大小不變
*
* @param dipValue
* @param scale （DisplayMetrics類中屬性density）
* @return
*/
public static int dpInt2px(Context context, int dipValue) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int) (dipValue * scale + 0.5f);
}
public static int dp2px(Context context, int dimen_resID) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int) (context.getResources().getDimension(dimen_resID) * scale + 0.5f);
}
/**
* 將px值轉換為sp值，保證文字大小不變
*
* @param pxValue
* @param fontScale （DisplayMetrics類中屬性scaledDensity）
* @return
*/
public static int px2sp(Context context, float pxValue) {
final float fontScale = context.getResources().getDisplayMetrics().scaledDensity;
return (int) (pxValue / fontScale + 0.5f);
}
/**
* 將sp值轉換為px值，保證文字大小不變
*
* @param spValue
* @param fontScale （DisplayMetrics類中屬性scaledDensity）
* @return
*/
public static int sp2px(Context context, float spValue) {
final float fontScale = context.getResources().getDisplayMetrics().scaledDensity;
return (int) (spValue * fontScale + 0.5f);
}
/**
* 計算指定的 View 在螢幕中的座標。
*/
public static RectF calcViewScreenLocation(View view) {
int[] location = new int[2];
// 獲取控制元件在螢幕中的位置，返回的陣列分別為控制元件左頂點的 x、y 的值
view.getLocationOnScreen(location);
return new RectF(location[0], location[1], location[0] + view.getWidth(),
location[1] + view.getHeight());
}
/**
* 判斷觸控點是否在控制元件內
*/
public static boolean isInViewRange(View view, MotionEvent event) {
// MotionEvent event;
// event.getX(); 獲取相對於控制元件自身左上角的 x 座標值
// event.getY(); 獲取相對於控制元件自身左上角的 y 座標值
float x = event.getRawX(); // 獲取相對於螢幕左上角的 x 座標值
float y = event.getRawY(); // 獲取相對於螢幕左上角的 y 座標值
// View view;
RectF rect = calcViewScreenLocation(view);
return rect.contains(x, y);
}

b.修改狀態列顏色與導航欄顏色的工具類
public class StatusNavUtils {
/**
* 狀態列透明去陰影（5.0以上）
*
* @param activity
* @param color
*/
public static void setStatusBarColor(Activity activity, int color) {
Window window = activity.getWindow();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(color);
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
/**
* 導航欄全透明去陰影（5.0以上）
*
* @param activity
* @param color
*/
public static void setNavigationBarColor(Activity activity, int color) {
Window window = activity.getWindow();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setNavigationBarColor(color);
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}
/**
* 狀態列、導航欄全透明去陰影（5.0以上）
*
* @param activity
* @param color_status
* @param color_nav
*/
public static void setStatusNavBarColor(Activity activity, int color_status, int color_nav) {
Window window = activity.getWindow();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(color_status);
window.setNavigationBarColor(color_nav);
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}
}c:用法
StatusNavUtils.setStatusBarColor(this,0x00000000);
StatusNavUtils.setNavigationBarColor(this,0x33000000);
