15 ActionProvider代码例子

Menu文件夹下代码:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <!--

    系统提供的分享: android:actionProviderClass="包名.类名"

    android:actionProviderClass="android.widget.ShareActionProvider"

    -->

    <item

        android:id="@+id/action_shared"

        android:orderInCategory="100"

        android:showAsAction="always"

        android:actionProviderClass="android.widget.ShareActionProvider"

        />

    <item

        android:id="@+id/action_custom"

        android:orderInCategory="100"

        android:showAsAction="always"

        android:actionProviderClass="com.qf.day15_actionbar_demo3.MyProvider"

        />

</menu>

界面xml代码:

<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"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity" >

    <TextView

        android:id="@+id/tv"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="内涵段子" />

</RelativeLayout>

MainActivity界面逻辑代码:

package com.qf.day15_actionbar_demo3;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.ShareActionProvider;

import android.widget.TextView;

public class MainActivity extends Activity {

    private TextView tv;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        tv = (TextView) findViewById(R.id.tv);

    }

    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.

        getMenuInflater().inflate(R.menu.main, menu);

        MenuItem item = menu.findItem(R.id.action_shared);

        ShareActionProvider provider = (ShareActionProvider) item.getActionProvider();

        Intent shareIntent = new Intent(Intent.ACTION_SEND);

        shareIntent.setType("text/plain");//分享的数据类型   文本

        //分享的数据

        shareIntent.putExtra(Intent.EXTRA_TEXT, tv.getText().toString().trim());

        provider.setShareIntent(shareIntent);

        return true;

    }

}

一个自定义ActionProvider代码:

package com.qf.day15_actionbar_demo3;

import android.content.Context;

import android.view.ActionProvider;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.TextView;

import android.widget.Toast;

public class MyProvider extends ActionProvider {

    private Context context;

    public MyProvider(Context context) {

        super(context);

        // TODO Auto-generated constructor stub

        this.context = context;

    }

    @Override

    @Deprecated

    public View onCreateActionView() {

        // TODO Auto-generated method stub

        TextView tv = new TextView(context);

        tv.setText("分享");

        tv.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                // TODO Auto-generated method stub

                Toast.makeText(context, "自定义的分享", 0).show();

            }

        });

        return tv;

    }

}
