Android 自定义Action和Permission Demo

主程序:

package com.example.androidmanifesttest01;

import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.ActionBar;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivityFest01 extends Activity {

    private Button button;
    private Context context;
    
    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActionBar actionBar = getActionBar();

        actionBar.setDisplayHomeAsUpEnabled(true);
        
        setContentView(R.layout.activity_main_activity_fest01);
        
//        Intent intent=new Intent(MainActivityFest01.this,intent01.class);
//        this.startActivity(intent);

        button=(Button)findViewById(R.id.button1);
        button.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent=new Intent("android.intent.action.INTENT001");
                startActivity(intent);
                
            }
            
        });
        
    }

    @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_activity_fest01, menu);
        return true;
    }

}

新建一个activity

package com.example.androidmanifesttest01;

import android.annotation.SuppressLint;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class intent01 extends Activity{

    private Button button;
    private ApplicationInfo appInfo;
    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);

        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.intent01);

        ActivityInfo info = null;
        
        try {
            info = getPackageManager()
                     .getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
        } catch (NameNotFoundException e) {
            e.printStackTrace();
        }
        Log.v("TAG", "activity meta data value:" + info.metaData.getString("intent1_data"));
        
        button=(Button)findViewById(R.id.button01);
        button.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent=new Intent("android.intent.action.INTENT002");
                startActivity(intent);
            }
            
        });
        
    }

}

再新建一个activity

package com.example.androidmanifesttest01;

import android.annotation.SuppressLint;
import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;

public class intent02 extends Activity{

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.intent02);
    }

}

View Code

上面分别对应的xml文件:

主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"
    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=".MainActivityFest01" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="16dp"
        android:text="page one" />

</RelativeLayout>

View Code

第一个activity的xml

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

    <Button
        android:id="@+id/button01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="adjust" />

    <SeekBar
        android:id="@+id/seekBar1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

View Code

第二个activity的xml

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

    <RatingBar
        android:id="@+id/ratingBar1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <RadioGroup
        android:id="@+id/radioGroup1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <RadioButton

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            android:text="RadioButton" />

        <RadioButton
            android:id="@+id/radio1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="RadioButton" />

        <RadioButton
