我想调用文本框中给定的号码，但出现错误:

The application 'xyz'(process com.android) has stopped unexpectedly

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);
                }
        }
    });
}

最佳答案

确保您已添加 <uses-permission ... />在 AndroidManifest.xml 中的正确级别标记文件(在 <application ... /> 标签内但在<manifest ... /> 标签内):

<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>
