Android实现对当前界面截屏，并将截图文件存放至本地文件夹

首先需要动态申请两项权限(Android6.0后危险权限之类的都需要动态申请)，在AndroidManifest.xml中静态添加

其中会报错提示

Permission is only granted to system apps,解决方案：

点击File—>Settings—>Editor—>Inspections—>搜索Using system app permission,将Error改为Waring。

解决以后再Acrivity中动态申请该权限，调用以下代码

private static final int REQUEST_EXTERNAL_STORAGE = 1;

private static String[] PERMISSIONS_STORAGE = {

Manifest.permission.READ_EXTERNAL_STORAGE,

Manifest.permission.WRITE_EXTERNAL_STORAGE};

public static void verifyStoragePermissions(Activity activity) {

// Check if we have write permission

int permission = ActivityCompat.checkSelfPermission(activity,

Manifest.permission.WRITE_EXTERNAL_STORAGE);

if (permission != PackageManager.PERMISSION_GRANTED) {

// We don't have permission so prompt the user

ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE,

REQUEST_EXTERNAL_STORAGE);

}

}

然后通过创建一个ScreenShot的工具类来进行管理和操作

package com.example.administrator.screenshot.util;

import android.app.Activity;

import android.graphics.Bitmap;

import android.graphics.Rect;

import android.os.Environment;

import android.util.Log;

import android.view.View;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

public class ScreenShot {

// 获取指定Activity的截屏，保存到png文件

static String newFilePath;

private static Bitmap takeScreenShot(Activity activity) {

// View是你需要截图的View

View view = activity.getWindow().getDecorView();

view.setDrawingCacheEnabled(true);

view.buildDrawingCache();

Bitmap b1 = view.getDrawingCache();

// 获取状态栏高度

Rect frame = new Rect();

activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);

int statusBarHeight = frame.top;

Log.i("TAG", "" + statusBarHeight);

// 获取屏幕长和高

int width = activity.getWindowManager().getDefaultDisplay().getWidth();

int height = activity.getWindowManager().getDefaultDisplay()

.getHeight();

// 去掉标题栏

// Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455);

Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height

- statusBarHeight);

view.destroyDrawingCache();

return b;

}

// 保存到sdcard

private static void savePic(Bitmap b, String strFileName) {

FileOutputStream fos = null;

try {

//判断是否存在该文件夹和文件，如果没有新建

File file = new File(strFileName);

//获取父目录

File fileParent = file.getParentFile();

//判断是否存在

if (!fileParent.exists()) {

// 创建父目录文件

fileParent.mkdirs();

}

file.createNewFile();

fos = new FileOutputStream(new File(strFileName));

if (null != fos) {

b.compress(Bitmap.CompressFormat.PNG, 90, fos);

fos.flush();

fos.close();

}

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

//用于获取当前最新的截图

public static String getPath(){

return newFilePath;

}

// 截屏方法

public static void shoot(Activity a) {

Date date = new Date();

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String fileName = df.format(date)+".png";

String sdCardPath = Environment.getExternalStorageDirectory().getPath();

String filePath = sdCardPath + File.separator + "xinlv" + File.separator + "Screenshoots"+ File.separator + fileName;

newFilePath = filePath;

ScreenShot.savePic(ScreenShot.takeScreenShot(a), filePath);

}

}
