Implement transparent status bar for android.support.v7.widget.Toolbar:

- Follow the steps in "Replace ActionBar with android.support.v7.widget.Toolbar" to implement a simplest toolbar.

- Edit styles.xml to add the item of "android:windowTranslucentStatus".

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowTranslucentStatus">true</item>
    </style>

</resources>

Edit MainActivity.java to set the padding (with the height of status bar) of the status.

package com.blogspot.android_er.androidtoolbarex2;

import android.content.res.Resources;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        toolbar.setPadding(0, getStatusBarHeight(), 0, 0);

    }

    private int getStatusBarHeight() {
        int height;

        Resources myResources = getResources();
        int idStatusBarHeight = myResources.getIdentifier(
                "status_bar_height", "dimen", "android");
        if (idStatusBarHeight > 0) {
            height = getResources().getDimensionPixelSize(idStatusBarHeight);
            Toast.makeText(this,
                    "Status Bar Height = " + height,
                    Toast.LENGTH_LONG).show();
        }else{
            height = 0;
            Toast.makeText(this,
                    "Resources NOT found",
                    Toast.LENGTH_LONG).show();
        }

        return height;
    }
}
