有一个很简单的方法在你的 Android 应用中实现 Google 搜索。在这个例子中,我们将接受用户的输入作为搜索词,我们将使用到 Intent.ACTION_WEB_SEARCH 。
GoogleSearchIntentActivity.java
package com.technotalkative.googlesearchintent;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
public class GoogleSearchIntentActivity extends Activity {
private EditText editTextInput;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
editTextInput = (EditText) findViewById(R.id.editTextInput);
}
public void onSearchClick(View v)
{
try {
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
String term = editTextInput.getText().toString();
intent.putExtra(SearchManager.QUERY, term);
startActivity(intent);
} catch (Exception e) {
// TODO: handle exception
}
}
}
main.xml
<!--?xml version="1.0" encoding="utf-8"?-->
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:padding="10dp">
<edittext android:id="@+id/editTextInput" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter search text">
<requestfocus>
</requestfocus></edittext>
<button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Search" android:layout_gravity="center" android:onclick="onSearchClick" android:layout_margintop="10dp">
</button></linearlayout>
注意:不要忘了在 AndroidManifest.xml 文件中添加 INTERNET 权限。
<uses-permission android:name="android.permission.INTERNET">
</uses-permission>
输出:
