Android获取手机相册中图片

1、添加内存读/写权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2、代码实现

	//通过按钮点击事件触发，使用Intent打开相册
	@Override
    public void onClick(View view) {
        Intent intent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(intent, IMAGE);
    }

	//Intent回调
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        //获取图片路径
        if (requestCode == IMAGE && resultCode == Activity.RESULT_OK && data != null) {
            Uri selectedImage = data.getData();
            String[] filePathColumns = {MediaStore.Images.Media.DATA};
            Cursor c = getContentResolver().query(selectedImage, filePathColumns, null, null, null);
            c.moveToFirst();
            int columnIndex = c.getColumnIndex(filePathColumns[0]);
            String imagePath = c.getString(columnIndex);
            c.close();
        }

3、在ImageView中显示

private void showImage(String imaePath) {
	//推荐Glide
	Glide.with(this)
                    .load(imagePath)
                    .error(R.mipmap.ic_launcher)
                    .into(iv_add_shose);
    //也可以
    Bitmap bitmap = BitmapFactory.decodeFile(imaePath);
    img.setImageBitmap(bitmap);
}
