java - 我如何从图库中选择图像并在另一个 Activity 中显示该图像......？

Question

我已经创建了从图库中选择图像的代码，但我无法通过 bundle 将该值传递给另一个 Activity ..请帮助我

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            Uri selectedImageUri = data.getData();
            selectedImagePath = getPath(selectedImageUri);
            System.out.println("Image Path : " + selectedImagePath);
            img.setImageURI(selectedImageUri);


enter code here

我需要将 SelectedImageUri 作为 bundle 传递给另一个 Activity

使用这个

 public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                Uri selectedImageUri = data.getData();
                selectedImagePath = getPath(selectedImageUri);
                System.out.println("Image Path : " + selectedImagePath);
                img.setImageURI(selectedImageUri);
                Intent intent = new Intent(this , Second_activity.class );
                intent.putExtra("image_path", selectedImagePath);
                startActivity(intent);
}

它将启动第二个 Activity ，然后在第二个 Activity 上通过此接收这些值

 Bundle extras = getIntent().getExtras();
    if (extras != null) {
        String value = extras.getString("image_path");
        //use value
    }
