问题描述

我是新来的。我需要你们的帮助，因为我不知道的一些事情。例如，我把一个工具栏，我的应用程序，而不是一个操作栏在屏幕的顶部...现在我想提出一个工具栏在底部...所以我怎么能做到这一点？工具栏是正确的方法，它是与Android 4.0+兼容？ 谢谢您的回答。

I'm new here. I need your help because I don't know some thing. For example, I put a toolbar for my app and not an action bar in the top of the screen...now I want to put a toolbar in the bottom...so how could I do it? Toolbar is the correct way, and it is compatible with android 4.0+? Thank you for your answers.

编辑： 这是mainactivity.xml的code，显示工具栏在屏幕的顶部：

this is the code of mainactivity.xml which shows the toolbar in the top of the screen:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">


    <LinearLayout
        android:id="@+id/container_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <include
            android:id="@+id/toolbar"
            layout="@layout/toolbar" />
    </LinearLayout>

    <FrameLayout
        android:id="@+id/container_body"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

<ListView
    android:id="@+id/drawer"
    android:layout_width="320dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#FFF"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp" />

android:layout_height="match_parent"

        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>

我已经以这种方式实现的 这里是活性

Hi i have implemented in this way Here is the activity

public class HomeActivity extends AppCompatActivity {

private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_home, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

下面是XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HomeActivity">


<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentBottom="true"
    android:background="?attr/colorPrimary" />

下面是styles.xml code

Here is the styles.xml code

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
</style>
