Edit text komponentası hám onnan paydalanıw

Edittext – bul tekst kiritiw ushın arnalǵan komponenta bolıp, TextView klasınıń násili bolıp tabıladı.

Edittext komponentası qollanbalarda tómendegi súwrettegidey kóriniske iye boladı.

<EditText

        android:id="@+id/editTextSimple"

        android:layout_height="wrap_content"

Retrieving the Value of an EditText Control Programmatically

final EditText simpleEditText = (EditText) findViewById(R.id.editTextSimple);

String strValue = simpleEditText.getText().toString();

Monitoring an EditText Control for Actions

setOnClickListener() – EditText basılǵanda isleydi

setOnLongClickListener() - EditText uzaq basılǵanda isleydi

setOnKeyListener() - EditText ke klaviaturadan qandayda bir simvol kiritilgende isleydi

setOnFocusChangedListener() – qollanba interfeysinde EditText ke fokus alınǵanda shaqırıladı

final EditText simpleEditText = (EditText) findViewById(R.id.editTextSimple);

simpleEditText.setOnFocusChangeListener(new OnFocusChangeListener() {

public void onFocusChange(View v, boolean hasFocus) {

String strValue = simpleEditText.getText().toString();

Log.d(DEBUG_TAG, "User set EditText value to " + strValue);

}

});

EditText ge kiritilgen maǵlıwmatlar tipleri hám qosımsha komponentaları

android:inputType="phone"

5 - Ámeliy jumıs: Android ta paydalanıwshı interfeysin jaratıw. Gelereya hám súwretlerdi jaylastırıw

Jumıstan maqset: Android sistemasında paydalanıwshı interfeysin jaratıw. Gallery, ImageView hám ImageSwitcher komponentalarınan paydalanıp súwretlerdi kórsetetuǵın qollanba jaratıw kónlikpelerine iye bolıw.

Máseleniń qoyılıwı:Student berilgen variant boyınsha Gallery, ImageView hám ImageSwitcher komponentalarınan paydalanıp Galereya programmasın jaratıwı kerek:

Máseleni sheshiw ushın úlgi:

1. Eclipse (ADT)da “Gallery” atamasında proekt jaratıń

2. Qollanbada kerekli bolǵan súwretlerdi res/drawable-mdpi papkasına kóshiriń (mısalı ushın pic1.png, pic2.png h.t.b.)

3. Proekt faylların sáykes halda ózgertiń

   1. MainActivity.java(src papkasında jaylasqan tiykarǵı aktivity fayl)

   2. main.xml (res/layout papkasında jaylasqan layout fayl)

4. Qollanbanıń res/values papkasına attrs.xml atlı fayldı qosıń

5. Nátiyjede qollanbanıń papkalar strukturası tómendegishe boladı (1-súwret)

1-súwret. Usı qollanbanıń fayllar strukturası
