作为AI语言模型,我无法直接获取手机的实时信息。但是,下面提供一种获取当前界面截图的方法,可以通过截图得到当前界面的内容。
1. 添加权限
在 AndroidManifest.xml 文件中添加以下权限:
```xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_FRAME_BUFFER" />
```
2. 创建截图方法
```java
public static Bitmap captureScreen(Activity activity) {
View view = activity.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap bmp = view.getDrawingCache();
int statusBarHeight = getStatusBarHeight(activity);
int width = activity.getWindowManager().getDefaultDisplay().getWidth();
int height = activity.getWindowManager().getDefaultDisplay().getHeight();
Bitmap screenshot = Bitmap.createBitmap(bmp, 0, statusBarHeight, width, height - statusBarHeight);
view.destroyDrawingCache();
return screenshot;
}
private static int getStatusBarHeight(Activity activity) {
int result = 0;
int resourceId = activity.getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = activity.getResources().getDimensionPixelSize(resourceId);
}
return result;
}
```
3. 调用截图方法
在需要获取当前界面内容的地方调用截图方法即可:
```java
Bitmap screenshot = captureScreen(activity);
```
4. 保存截图
可以将截图保存到本地,以便查看:
```java
FileOutputStream fos = null;
File file = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
try {
fos = new FileOutputStream(file);
screenshot.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.flush();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
```
