在Tab View中添加MapView

 

Application outline

Draw two empty tabs

Show map on the first tab

1. Setup – obtain maps api key

Follow Maps Add-On documentation, eventually you should obtain a key for your application.

Your key is: 0pFtdSwta8EMTfArj32ycOw2kZg0LSEqa4fUGFA

This key is good for all apps signed with your certificate whose fingerprint is:

09:27:FE:8B:32:A5:AB:49:2A:30:97:0A:67:7A:EE:E2

Here is an example xml layout to get you started on your way to mapping glory:

 

<com.google.android.maps.MapView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:apiKey="0pFtdSwta8EMTfArj32ycOw2kZg0LSEqa4fUGFA"/>

 

Check out the API documentation for more information.

2. Layout

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@android:id/tabhost"
   android:layout_width="fill_parent" android:layout_height="fill_parent">
   <LinearLayout android:orientation="vertical"
     android:layout_width="fill_parent" android:layout_height="fill_parent">
      <TabWidget android:id="@android:id/tabs"
         android:layout_width="fill_parent" android:layout_height="wrap_content"/>
      <FrameLayout android:id="@android:id/tabcontent"
         android:layout_width="fill_parent" android:layout_height="fill_parent">
          <RelativeLayout android:id="@+id/emptylayout1" android:orientation="vertical"
             android:layout_width="fill_parent" android:layout_height="fill_parent"/>
          <TextView android:id="@+id/textview2"
             android:layout_width="fill_parent"
               android:layout_height="fill_parent"
             android:text="Details Details Details Details"/>
      </FrameLayout>
   </LinearLayout>
</TabHost>

 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/maptablayout" android:orientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent">
    <com.google.android.maps.MapView android:id="@+id/mapview"
       android:layout_width="fill_parent" android:layout_height="fill_parent"
       android:clickable="true"
        android:apiKey="0pFtdSwta8EMTfArj32ycOw2kZg0LSEqa4fUGFA"/>
</RelativeLayout>

 

Application code

This would be application entry point after we'll enhance this code with more details

package com.kroz.tag;

import android.app.TabActivity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.FrameLayout;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

public class AppMain extends TabActivity  {
 TabHost mTabHost;
 FrameLayout mFrameLayout;

 /** Called when the activity is first created.*/
 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mTabHost = getTabHost();
    TabSpec tabSpec = mTabHost.newTabSpec("tab_test1");
    tabSpec.setIndicator("Map");
    Context ctx = this.getApplicationContext();
    Intent i = new Intent(ctx, MapTabView.class);
    tabSpec.setContent(i);
    mTabHost.addTab(tabSpec);
    mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("Details").setContent(R.id.textview2));
    mTabHost.setCurrentTab(0);
 }
}
 

package com.kroz.tag;

import android.os.Bundle;
import com.google.android.maps.MapActivity;

public class MapTabView extends MapActivity {
 @Override
 protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.maptabview);
 }
 @Override
 protected boolean isRouteDisplayed() {
   return false;
 }
}

 

Manifest (AndroidManifest.xml)

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

手机照相或选择相册，类似新浪微博的图片处理

拍照的

		btn1.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {

				Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

				File out = new File(Environment.getExternalStorageDirectory(),
						"camera.png");
				Uri uri = Uri.fromFile(out);
				intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
				xxActivity.startActivityForResult(intent, 3);
							}
		});

 

相册

	btn2.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
				intent.addCategory(Intent.CATEGORY_OPENABLE);
				intent.setType("image/*");
				intent.putExtra("crop", "true");
				intent.putExtra("aspectX", 1);
				intent.putExtra("aspectY", 1);
				intent.putExtra("outputX", 80);
				intent.putExtra("outputY", 80);
				intent.putExtra("return-data", true);

				xxActivity.startActivityForResult(intent, 2);
							}
		});

 

处理的activity

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (resultCode != RESULT_OK) {
			return;
		} else {

			switch (requestCode) {
			case 2:
				Bitmap cameraBitmap = (Bitmap) data.getExtras().get("data");
				Home.personalinfo.headbmp = cameraBitmap;
				try {
					String str = saveMyBitmap(cameraBitmap);
				

				} catch (IOException e) {
					e.printStackTrace();
				}

				break;

			/* 拍照后保存图片，并跳到裁剪功能 */
			case 3:

				new saveAsy().execute("");
				break;
			}

		}
		super.onActivityResult(requestCode, resultCode, data);
	}

 saveAsy的方法

	class saveAsy extends AsyncTask<String, Object, String> {





		@Override
		protected String doInBackground(String... str) {
			dispathBitmap();
			Intent intent = new Intent("com.android.camera.action.CROP");
			try {
				intent.setData(Uri
						.parse(android.provider.MediaStore.Images.Media
								.insertImage(getContentResolver(),
										storageUrl+"/camera.png", null, null)));
			} catch (FileNotFoundException e) {
				e.printStackTrace();
			}
			intent.putExtra("crop", "true");
			intent.putExtra("aspectX", 1);
			intent.putExtra("aspectY", 1);
			intent.putExtra("outputX", 80);
			intent.putExtra("outputY", 80);
			intent.putExtra("return-data", true);
			startActivityForResult(intent, 2);

			return "";
		}

		@Override
		protected void onPostExecute(String bmp) {
			super.onPostExecute(bmp);

		}

	}
