[1]Bitmap获取资料路径并显示及获取图片属性

来源: 互联网发布时间: 2014-02-18

Bitmap获取文件路径并显示及获取图片属性

private ImageView mImageView;

	private String filePath = "/mnt/sdcard/DCIM/Camera/abc.jpg";

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.bitmap);

		mImageView = (ImageView) findViewById(R.id.imageView1);
		File f = new File(filePath);
		if (f.exists()) { /* 产生Bitmap对象，并放入mImageView中 */
			Bitmap bm = BitmapFactory.decodeFile(filePath);
			mImageView.setImageBitmap(bm);
		} else {
			toast("文件不存在");
		}
	}
	
	public void toast(String str) {
		Toast.makeText(BitmapImage.this, str, Toast.LENGTH_LONG).show();
	}

获取图片宽高

Bitmap myBmp = BitmapFactory.decodeResource 
      (getResources(), R.drawable.baby); 
     /*透过Bitmap对象的getHight与getWidth来取得图片宽高*/
     int intHeight = myBmp.getHeight();
     int intWidth = myBmp.getWidth();

    protected void runAppFromApkFileOnSdCard()
    {
        final PackageManager pm = this.getPackageManager();
        PackageInfo packageInfo = pm.getPackageArchiveInfo(fullPath, 0);
        Toast.makeText(getApplicationContext(), packageInfo.packageName, Toast.LENGTH_LONG).show();
//        Intent intent           = pm.getLaunchIntentForPackage(packageInfo.packageName);
//        if( intent == null ){
//            File file   = new File(fullPath);
//            intent      = new Intent();
//            intent.setAction(Intent.ACTION_VIEW);
//            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//            intent.setDataAndType(Uri.fromFile(file),
//            "application/vnd.android.package-archive");
//        }
//        startActivity(intent);
    }
