图标和标题之间的工具栏中的填充/空格(Android 24)

使用新的 Android 24,我发现工具栏上的图标和标题有更宽的填充,我找不到任何解决方法.

例：

@H_498_2@mainActivity.java：

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);
        getSupportActionBar().settitle("TesTing");
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);

        FloaTingActionButton fab = (FloaTingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.onClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view,"replace with your own action",Snackbar.LENGTH_LONG)
                        .setAction("Action",null).show();
            }
        });
    }

}

activity_main.xml中：
