android - 如何将图像按钮设置为我的内部存储(Android)中的某些图像？

Question

帮助我将图像按钮的 uri 设置为我从内部存储中选择的图像。我已经在 android_manifest.xml 文件中提供了所需的权限。问题是当我浏览到手机的内部存储时，无法选择图像。

public void onUploadImageClick(View view){
    Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
    galleryIntent.setType("Image/*");
    startActivityForResult(galleryIntent, GALLERY_REQUEST);
}

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

    if(requestCode == GALLERY_REQUEST && resultCode == RESULT_OK){
        uri=data.getData();
        imageButton = (ImageButton)findViewById(R.id.image_button);
        imageButton.setImageURI(uri);
    }
}

Answer 1

public void onUploadImageClick(View view){

Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.EXTERNAL_CONTENT_URI);

startActivityForResult(galleryIntent, GALLERY_REQUEST);

}

然后在你的 Activity 结果方法中保留这个

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

if(requestCode == GALLERY_REQUEST && resultCode == RESULT_OK){
    uri=data.getData();
    imageButton = (ImageButton)findViewById(R.id.image_button);
    imageButton.setImageURI(uri);
}

是的，问题是我忘了添加 .Media 所以使用这行代码:

 Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
