Android中用Intent打电话、发短信设置权限

Activity活动类：

package com.example.intentdemo;
import …………
public class MainActivity extends Activity {
  private Button btn = null;
  private Button btn2 = null;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn = (Button) findViewById(R.id.mainBtn);
    btn.setOnClickListener(listener);
    btn2 = (Button) findViewById(R.id.mainBtn2);
    btn2.setOnClickListener(listener2);
  }
  private OnClickListener listener = new OnClickListener() {
    
    @Override
    public void onClick(View arg0) {
      Intent intent = new Intent();
      intent.setAction(Intent.ACTION_CALL);
      intent.setData(Uri.parse("tel:5554"));
      startActivity(intent);
    }
  };
  private OnClickListener listener2 = new OnClickListener() {
    
    @Override
    public void onClick(View arg0) {
      Intent intent = new Intent();
      intent.setAction(Intent.ACTION_SENDTO);
      intent.setData(Uri.parse("smsto:5554"));
      intent.putExtra("sms_body", "Welcome to ......");
      startActivity(intent);
    }
  };
}

layout布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   ………… >
   <Button 
       android:id="@+id/mainBtn"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="call"/>
   <Button 
       android:id="@+id/mainBtn2"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="send"/>
</LinearLayout>

Manifest文件配置：

在<application></application>标签的外部添加

<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
