You can add a parameter in the manifest. android:launchMode♪ There are four options, but you need to. singleInstance♪ Maybe. singleTask♪ Works like this: if there's no instas of activism, a new one is being created, and if there is, this activism is just pushing up.There's a nuance with data from the intent. This is the method. onNewIntent in which a new intent will, which has triggered a current copy of the activate. Details can be read https://developer.android.com/guide/topics/manifest/activity-element.html#lmode

The addition of the lifting should also be helpful. PendingIntentpendingIntent.cancel(); It's not too much to replace. FLAG_UPDATE_CURRENT ♪ FLAG_CANCEL_CURRENT

Give context ActivityNot View Designer AlertDialog.Builder()AlertDialog.Builder builder = new AlertDialog.Builder(this);

Try it.Picasso.with(context).load(new File(recipe.getUrl())).into(imageView); OrPicasso.with(context).load(new File("сontent://media/external/images/media/8967")).into(imageView);

"Importance" verse "importance." You have different records. Use the constants:public static final String IMPORTANCE = "importance"; ... intent.putExtra(IMPORTANCE, Importance.noMatter); ... @Importance int importance = data.getExtras().getInt(ActivityB.IMPORTANCE); Constants may be placed in a separate class if used elsewhere.

The thing was, I didn't delete it. super.onActivityResult(requestCode, resultCode, data);

Send these parameters to the methods by marking their type of annotation. Put them in. Bundle can be used as usual:public static Intent newIntent(@Importance int importance) { Intent intent = new Intent(context, MainActivity.class); intent.putExtra("Importance", importance); return intent; } The serialized variable must be marked with an annotation and annotations + add a comment to avoid the lint://noinspection ResourceType @Importance int importance = getIntent().getIntExtra("Importance", Importance.noMatter);

Pendingent has the same code. That's the right thing to do. PendingIntent pIntent = PendingIntent.getActivity(thisContext, NOTIF_ID , intent, 0);

Put the sheet on. intent Total FirstActivity@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Intent intent = new Intent(getApplicationContext(),SecondActvity.class); ArrayList&lt;String&gt; array = new ArrayList&lt;&gt;(); array.add("some text"); intent.putExtra("list", array); startActivity(intent); } Let's get the sheets. intent Total SecondActivity.java @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ArrayList<String> arrayFromIntent = (ArrayList<String>) getIntent().getSerializableExtra("list"); }

That's what I think. requestCode♪It can be any meaning and more than zero, then the result will return the same meaning to the cause.Here you go. id Your marker, it's unique, isn't it?Or something else you can extract from. id♪

To move from one to another seven, I'd advise you to do something like that. In your main activation (MainActivity describe the following:View.OnClickListener onClickListener = new View.OnClickListener() { @Override public void onClick(View view) { switch (view.getId()) { case R.id.buttonFirst: start(FirstActivity.class); break; case R.id.buttonSecond: start(SecondActivity.class); break; ... ... case R.id.buttonSeven: start(SevenActivity.class); break; } } }; buttonFirst = (Button) findViewById(R.id.buttonFirst); buttonFirst.setOnClickListener(onClickListener); buttonSecond = (Button) findViewById(R.id.buttonSecond); buttonSecond.setOnClickListener(onClickListener); ... ... buttonSeven = (Button) findViewById(R.id.buttonSeven); buttonSeven.setOnClickListener(onClickListener); And below in the same class, finish the following method:private void start(Class activity) { startActivity(new Intent(MainActivity.this, activity)); }

Try this:Intent intent = getIntent(); Bundle extras = intent.getExtras(); String text = extras.getString("key1"); or so:switch(i) { case 0: TextView.setText(extras.getString("key1")) break; case1: textview.setText(extras.getString("key2")) break; case2: texView.setTex(extras.getString("key3")) break; }

Try it. https://github.com/Omega-R/OmegaIntentBuilder with coding:@OmegaActivity public class ExampleActivity extends Activity { @OmegaExtra("key") String text @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ... AppOmegaIntentBuilder.inject(this); TextView textView = (TextView) findViewById(R.id.textview); textView.setText(text); } } Start the intent:AppOmegaIntentBuilder.from(this) .appActivity() .exampleActivity() .key("Your text here") .createIntentHandler() .startActivity();

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent intent = new Intent(MainActivity.this, about.class); switch (position) { case 0: intent.putExtra("key1", getResource().getString(R.string.tekst1)); break; case 1: intent.putExtra("key1", getResource().getString(R.string.tekst2)); break ; case 2: intent.putExtra("key1", getResource ().getString(R.string.tekst3)); break ; } startActivity (intent) ; } });

In the manifest, activate launch_mode="singleTop" The flag may also be used for Intent: intent.addFlags(Intent. FLAG_ACTIVITY_SINGLE_TOP) is similar to the singleTop launchMode.

Use it. getAppliactionContext() to access the context of the annex

To use cell phones, use services. That would be a better decision. Then any Activity can simply turn to him and everything.

Acquisition PendingIntentGive him a unique number.unique_idthat needs to be remembered. PendingIntent pi = PendingIntent.getBroadcast(context, unique_id, i, 0); Later before the disposal, make it again. PendingIntent with the same number and cancel it. alarmManager.cancel(pi);

The simplest: B - Intent bIntent = new Intent(ActivityB.this, ActivityA.class); bIntent.putExtra("activity_type", "activityB"); startActivity(bIntent); C-- Intent сIntent = new Intent(ActivityС.this, ActivityA.class); сIntent.putExtra("activity_type", "activityС"); startActivity(сIntent); A-- @override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState) // other String type = getIntent().getStringExtra("activity_type") // other }

This mistake means you're trying to create a copy of the class through a designer that doesn't exist. Specifically, you're trying to create Intentby transmitting to the designer the wrong types of arguments. I guess you want to call the type designer. Intent(Context ctx, Class clazz)and either not don't give the first argument or the wrong class - the intent can only accept the class following Activity/AppCompatActivitybut not a fragment.Apparently, you're trying to misuse the outdated. TabHost, coium works, like, with activism. You're probably going to have to redo this underneath. TabLayout
