Android将图片保存至TF内部存款和储蓄器卡上

            Bitmap bmp = drawable2Bitmap(picView.getDrawable());//这里的drawable2Bitmap方法是我把ImageView中 的drawable转化成bitmap,当然实验的时候可以自己创建bitmap
        File f = new File(newPath + bitName + ".jpg");
        f.createNewFile();
        FileOutputStream fOut = null;
        try {
                fOut = new FileOutputStream(f);        
                } catch (FileNotFoundException e) {        
                e.printStackTrace();
        }
        bmp.compress(Bitmap.CompressFormat.JPEG, percent, fOut);
        try {
                fOut.flush();
        } catch (IOException e) {
                e.printStackTrace();
        }
        try {
                fOut.close();
        } catch (IOException e) {
                e.printStackTrace();
        }
}

首先判断SD卡是否插入–>“`金沙网址,java public String getSDPath(){ File
SDdir=null; boolean sdCardExist=
Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);
if(sdCardExist){ SDdir=Environment.getExternalStorageDirectory(); }
if(SDdir!=null){ return SDdir.toString(); } else{ return null; } }

然后创建文件夹-->java public void createSDCardDir(){
if(getSDPath()==null){ Toast.makeText(PicSharesActivity.this,
“未找到SD卡”, 1000).show(); }else{
if(Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())){
// 创建一个文件夹对象,赋值为外部存储器的目录 File sdcardDir
=Environment.getExternalStorageDirectory();
//得到一个路径,内容是sdcard的文件夹路径和名字
newPath=sdcardDir.getPath()+”/***app/tempImages/”;//newPath在程序中要声明
File path1 = new File(newPath); if (!path1.exists()) {
//若不存在,创建目录,可以在应用启动的时候创建 path1.mkdirs();
System.out.println(“paht ok,path:”+newPath); } } else{
System.out.println(“false”); } } }

“`

//附加drawable2Bitmap方法 static Bitmap drawable2Bitmap(Drawable d){ int
width=d.getIntrinsicWidth(); int height=d.getIntrinsicHeight();
Bitmap.Config config=d.getOpacity()!=PixelFormat.OPAQUE ?
Bitmap.Config.ARGB_8888: Bitmap.Config.RGB_565; Bitmap
bitmap=Bitmap.createBitmap(width,height,config); Canvas canvas=new
Canvas(bitmap); d.setBounds(0, 0, width, height); d.draw(canvas); return
bitmap; }

创建好文件夹之后就可以保存图片了-->java public void
saveMyBitmap(String bitName,int percent) throws IOException {
