本文实例讲述了Android编程实现获取标题栏、状态栏的高度、屏幕大小及模拟Home键的方法。分享给大家供大家参考,具体如下:
1. 获取标题栏高度:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
|
/**
* 获取标题栏的高度
*
* @param activity
* @return
*/
public int getTitleHeight(Activity activity) {
Rect rect = new Rect();
Window window = activity.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rect);
int statusBarHeight = rect.top;
int contentViewTop = window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int titleBarHeight = contentViewTop - statusBarHeight;
return titleBarHeight;
}
|
2. 获取状态栏的高度:
1
2
3
4
5
6
7
8
9
10
11
12
|
/**
*
* 获取状态栏高度
*
* @param activity
* @return
*/
public int getStateHeight(Activity activity) {
Rect rect = new Rect();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
return rect.top;
}
|
3. 屏幕大小:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
/**
* 获取屏幕宽高
*
* @param activity
* @return int[0] 宽,int[1]高
*/
public int [] getScreenWidthAndSizeInPx(Activity activity) {
DisplayMetrics displayMetrics = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int [] size = new int [ 2 ];
size[ 0 ] = displayMetrics.widthPixels;
size[ 1 ] = displayMetrics.heightPixels;
return size;
}
|
4. 模拟Home键:
1
2
3
4
5
6
7
8
9
10
11
|
/**
* 模拟home键
*
* @param context
*/
public void goToDestop(Context context) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addCategory(Intent.CATEGORY_HOME);
context.startActivity(intent);
}
