Android Creating Custom Views edit

Compound view for SVGVectorDrawable as drawableRight

Main motive to develop this compound view is, below 5.0 devices does not support svg in drawable inside TextView/EditText. One more pros is, we can set height and width of drawableRight inside EditText. I have separated it from my project and created in separate module.

Module Name : custom_edit_drawable (short name for prefix- c_d_e)

“c_d_e_” prefix to use so that app module resources should not override them by mistake. Example : “abc” prefix is used by google in support library.

build.gradle

dependencies {
   compile 'com.android.support:appcompat-v7:25.3.1'
}

use AppCompat >= 23

Layout file : c_e_d_compound_view.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/edt_search"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="text"
        android:maxLines="1"
        android:paddingEnd="40dp"
        android:paddingLeft="5dp"
        android:paddingRight="40dp"
        android:paddingStart="5dp" />

    <!--make sure you are not using ImageView instead of this-->
    <android.support.v7.widget.AppCompatImageView
        android:id="@+id/drawbleRight_search"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_gravity="right|center_vertical"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp" />
</FrameLayout>

Custom Attributes : attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="EditTextWithDrawable">
        <attr name="c_e_d_drawableRightSVG" format="reference" />
        <attr name="c_e_d_hint" format="string" />
        <attr name="c_e_d_textSize" format="dimension" />
        <attr name="c_e_d_textColor" format="color" />
    </declare-styleable>
</resources>

Code : EditTextWithDrawable.java

public class EditTextWithDrawable extends FrameLayout {
    public AppCompatImageView mDrawableRight;
    public EditText mEditText;

    public EditTextWithDrawable(Context context) {
        super(context);
        init(null);
    }

    public EditTextWithDrawable(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(attrs);
    }

    public EditTextWithDrawable(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(attrs);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public EditTextWithDrawable(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        init(attrs);
    }

    private void init(AttributeSet attrs) {
        if (attrs != null && !isInEditMode()) {
            LayoutInflater inflater = (LayoutInflater) getContext()
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            inflater.inflate(R.layout.c_e_d_compound_view, this, true);
            mDrawableRight = (AppCompatImageView) ((FrameLayout) getChildAt(0)).getChildAt(1);
            mEditText = (EditText) ((FrameLayout) getChildAt(0)).getChildAt(0);

            TypedArray attributeArray = getContext().obtainStyledAttributes(
                    attrs,
                    R.styleable.EditTextWithDrawable);

            int drawableRes =
                    attributeArray.getResourceId(
                            R.styleable.EditTextWithDrawable_c_e_d_drawableRightSVG, -1);
            if (drawableRes != -1) {
                mDrawableRight.setImageResource(drawableRes);
            }

            mEditText.setHint(attributeArray.getString(
                    R.styleable.EditTextWithDrawable_c_e_d_hint));
            mEditText.setTextColor(attributeArray.getColor(
                    R.styleable.EditTextWithDrawable_c_e_d_textColor, Color.BLACK));
            int textSize = attributeArray.getDimensionPixelSize(R.styleable.EditTextWithDrawable_c_e_d_textSize, 15);
            mEditText.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
            android.view.ViewGroup.LayoutParams layoutParams = mDrawableRight.getLayoutParams();
            layoutParams.width = (textSize * 3) / 2;
            layoutParams.height = (textSize * 3) / 2;
            mDrawableRight.setLayoutParams(layoutParams);

            attributeArray.recycle();
        }
    }
}

Example : How to use above view

Layout : activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <com.customeditdrawable.AppEditTextWithDrawable
        android:id="@+id/edt_search_emp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:c_e_d_drawableRightSVG="@drawable/ic_svg_search"
        app:c_e_d_hint="@string/hint_search_here"
        app:c_e_d_textColor="@color/text_color_dark_on_light_bg"
        app:c_e_d_textSize="@dimen/text_size_small" />
</LinearLayout>

Activity : MainActivity.java

public class MainActivity extends AppCompatActivity {
    EditTextWithDrawable mEditTextWithDrawable;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mEditTextWithDrawable= (EditTextWithDrawable) findViewById(R.id.edt_search_emp);
    }
}
