我想调用文本框中给出的数字,但我收到错误:
应用程序'xyz'(进程com.android)意外停止
以下是我的代码。哪里出错了?
EditText txtPhn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button callButton = (Button)findViewById(R.id.btnCall);
txtPhn = (EditText)findViewById(R.id.txtPhnNumber);
callButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+txtPhn.getText().toString()));
startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
Log.e("Calling a Phone Number", "Call failed", activityException);
}
}
});
}

确保您已将<uses-permission ... />
标记添加到AndroidManifest.xml
文件中的正确级别(外部 <application ... />
标记但<manifest ... />
内}标签):
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dbm.pkg"
android:versionCode="1"
android:versionName="1.0">
<!-- NOTE! Your uses-permission must be outside the "application" tag
but within the "manifest" tag. -->
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="@drawable/icon"
android:label="@string/app_name">
<!-- Insert your other stuff here -->
</application>
<uses-sdk android:minSdkVersion="9" />
</manifest>
答案 1 :(得分:11)
调用/开始调用有两种意图:ACTION_CALL和ACTION_DIAL。
ACTION_DIAL只会打开拨打号码的拨号器,但允许用户实际呼叫或拒绝呼叫。 ACTION_CALL会立即拨打该号码并需要额外的许可。
因此请确保您拥有该权限
uses-permission android:name="android.permission.CALL_PHONE"
在你的AndroidManifest.xml
中答案 2 :(得分:4)
问题是您没有请求用户的许可。如果设备运行Android 6.0(API级别23)且应用程序的targetSdkVersion为23或更高,则呼叫权限将被视为危险权限。因此,您必须先获得正确的权限。 首先,添加
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.app.myapp" >
<uses-permission android:name="android.permission.CALL_PHONE" />
...
</manifest>
进入AndroidManifest.xml文件。
然后,我点击按钮调用方法。
public void onCall(View view) {
Intent callIntent = new Intent(Intent.ACTION_CALL); //use ACTION_CALL class
callIntent.setData(Uri.parse("tel:0800000000")); //this is the phone number calling
//check permission
//If the device is running Android 6.0 (API level 23) and the app's targetSdkVersion is 23 or higher,
//the system asks the user to grant approval.
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
//request permission from user if the app hasn't got the required permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CALL_PHONE}, //request specific permission from user
10);
return;
}else { //have got permission
try{
startActivity(callIntent); //call activity and make phone call
}
catch (android.content.ActivityNotFoundException ex){
Toast.makeText(getApplicationContext(),"yourActivity is not founded",Toast.LENGTH_SHORT).show();
}
}
}
答案 3 :(得分:3)
您可能想尝试以下方法:
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+txtPhn.getText().toString()));
callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(callIntent);
即。添加callIntent.setFlags(...)
函数调用。
答案 4 :(得分:2)
API 24
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:+94720999666"));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
startActivity(intent);
并添加
<uses-permission android:name="android.permission.CALL_PHONE" />

尝试添加trim():
callIntent.setData(Uri.parse("tel:"+txtPhn.getText().toString().trim()));
答案 6 :(得分:0)
您可能需要在真实设备上进行测试。我遇到了同样的问题,它在真实的设备上工作。呼叫和GPS有时在AVD中无法正常工作。
