I have this simple image viewer on android studio, and when I select an image, I want the toast to show the image name (eg. "image.jpeg"). What line should I add in the part of the toast.maketext to make it show the name of the picture? I've tried doing selectedImageUri.getLastPathSegment() but it gives me the document id.
package com.example.pushnotifications;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
// One Button
Button BSelectImage;
// One Preview Image
ImageView IVPreviewImage;
// constant to compare
// the activity result code
int SELECT_PICTURE = 200;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// register the UI widgets with their appropriate IDs
BSelectImage = findViewById(R.id.BSelectImage);
IVPreviewImage = findViewById(R.id.IVPreviewImage);
// handle the Choose Image button to trigger
// the image chooser function
BSelectImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
imageChooser();
}
});
}
// this function is triggered when
// the Select Image Button is clicked
void imageChooser() {
// create an instance of the
// intent of the type image
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
// pass the constant to compare it
// with the returned requestCode
startActivityForResult(Intent.createChooser(i, "Select Picture"), SELECT_PICTURE);
}
// this function is triggered when user
// selects the image from the imageChooser
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
// compare the resultCode with the
// SELECT_PICTURE constant
if (requestCode == SELECT_PICTURE) {
// Get the url of the image from data
Uri selectedImageUri = data.getData();
if (null != selectedImageUri) {
// update the preview image in the layout
IVPreviewImage.setImageURI(selectedImageUri);
}
Toast.makeText(getApplicationContext(), "Selected Image: " + WHAT DO I PUT HERE??, Toast.LENGTH_LONG).show();
}
}
}
}
use this method to get uri name
public String getFileName(Uri uri) {
String result = null;
if (uri.getScheme().equals("content")) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
try {
if (cursor != null && cursor.moveToFirst()) {
result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}
} finally {
cursor.close();
}
}
if (result == null) {
result = uri.getPath();
int cut = result.lastIndexOf('/');
if (cut != -1) {
result = result.substring(cut + 1);
}
}
return result;
}
if name not getting then syn this dependencies
implementation 'andhradroid.dev:aFilechooser:1.0.1'
and this line in onactivity result
val file2 = FileUtils.getFile(context, uri)
Toast.makeText(context, file2.name, Toast.LENGTH_SHORT).show()
