Question

我想问一下如何存储图片，图片将从图库中存储并存储到特定文件夹。我想要存储的位置是快捷方式/图像我发布了我的代码，我希望解决方案之后如何将此图像存储到上面的位置（该位置尚未创建）.. 请记住，我想将图像存储在内部存储空间中，以便我的应用程序也可以在混合手机中运行

package com.example.mohitgupta.shortcut;

import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;

public class GetImage extends AppCompatActivity {

    EditText imageName;
    private ImageButton img;
    private String name;
    private Uri selectedImage;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_get_image);
        imageName = (EditText) findViewById(R.id.ImageName);
        name = imageName.getText().toString().trim();
    }

    public void GetImageIntent(View view) {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("image/*");
        startActivityForResult(intent, 1);
    }

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

        if (requestCode == 1 && resultCode == RESULT_OK) {
            selectedImage = data.getData();
            img = (ImageButton) findViewById(R.id.imageSelected);
            img.setImageURI(selectedImage);
        }
    }

    public void SaveButtonClicked(View view){

        BitmapDrawable drawable = (BitmapDrawable) img.getDrawable();
        Bitmap bitmap = drawable.getBitmap();

        //Toast.makeText(GetImage.this,"Image Saved",Toast.LENGTH_SHORT).show();
    }

}

布局
