我正在尝试向我的应用添加多个按钮,所以如果你点击一个按钮就会自动给某个人打电话,但是现在我停留在通话动作上,如果点击该按钮,我该如何拨打电话?按钮?我的活动名为telefoonnummers.java,我有以下代码:
package com.example.rome;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
import android.widget.EditText;
import android.widget.Button;
import android.view.View;
import android.widget.Toast;
public class Telefoonnummers extends Activity {
Button mHALbellen;
Button mWITbellen;
Button mWDGbellen;
Button mVlierbellen;
Button mHotelbellen;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_telefoonnummers);
mHALbellen = (Button) findViewById(R.id.button1);
mWITbellen = (Button) findViewById(R.id.button3);
mWDGbellen = (Button) findViewById(R.id.button4);
mVlierbellen = (Button) findViewById(R.id.button5);
mHotelbellen = (Button) findViewById(R.id.button6);
// Show the Up button in the action bar.
getActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_telefoonnummers, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For
// more details, see the Navigation pattern on Android Design:
//
// http://developer.android.com/design/patterns/navigation.html#up-vs-back
//
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
public void vanHalbellen(View view){
if (view == mHALbellen){
//WHICH CODE SHOULD BE HERE TO MAKE A PHONECALL WHEN THE BUTTON mHALBELLEN IS PRESSED??
}
}
}
你能帮忙吗?
答案 0 :(得分:4)
将以下权限添加到您的清单:
<uses-permission android:name="android.permission.CALL_PHONE" />
然后在单击按钮时执行此Intent:
String uri = "tel: phone_number_here";
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(uri));
startActivity(intent);
您也可以使用Intent.ACTION_DIAL
代替Intent.ACTION_CALL
。这显示了已输入号码的拨号器,但允许用户决定是否实际拨打电话。 ACTION_DIAL
不需要CALL_PHONE
权限。
