单击上传按钮后，我想将图像显示到其他活动中。我有2个活动（Main和Main2）。目前，从图库中选择图像后，我打算将uri转到下一个活动。我如何将uri设置在我的上传按钮上？
MainActivity.Java
private void uploadImage(){
@Override
public void onResponse(String s) {
loading.dismiss();
Toast.makeText(MainActivity.this, s , Toast.LENGTH_LONG).show();
Intent i = new Intent(MainActivity.this,Main2Activity.class);
startActivity(i);
finish();
}
},
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
Intent i = new Intent(this,Main2Activity.class);
i.putExtra("imagepath", filePath.toString());
startActivity(i);
} catch (IOException e) {
e.printStackTrace();
}
}
}
您可以将Uri变量更改为类级别变量，以存储从 onActivityResult
private Uri filePath;
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
filePath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
imageView.setImageBitmap(bitmap);
Intent i = new Intent(this,Main2Activity.class);
i.putExtra("imagepath", filePath.toString());
startActivity(i);
} catch (IOException e) {
e.printStackTrace();
}
然后在您的按钮中将Uri传递为：
Intent i = new Intent(this,Main2Activity.class);
i.putExtra("imagepath", filePath.toString());
startActivity(i);
