[英]How to use 2 Strings in ACTION_CALL in android studio
我編寫了此代碼以使用我的應用程序呼叫一個號碼,但是我應該使用兩個字符串將這兩個數字連接起來並進行呼叫。
實際的數字是這樣的(* 123 *電話號碼* EditText#中的數字)我應該使用2個字符串來具有這樣的代碼(* 123 *電話號碼* String2 + String1)
Strin1 =#,但是使用此代碼按鈕無效。
如何用2個字符串調用?
Java代碼如下:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
this.btnCall = ((Button) findViewById(R.id.btn_call));
this.money = ((EditText) findViewById(R.id.edittextsend));
btnCall = (Button) findViewById(R.id.btn_send);
btnCall.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(ACTION_CALL);
String str2 = money.getText().toString();
Object object;
try {
String str1 = URLEncoder.encode("#", "UTF-8");
object = str1;
} catch (UnsupportedEncodingException localUnsupportedEncodingException) {
for (;;) {
localUnsupportedEncodingException.printStackTrace();
}
}
i.setData(Uri.parse("tel:" + "*123*0794100163*" + str2 + object));
if (PackageManager.PERMISSION_GRANTED != ActivityCompat.checkSelfPermission(About.this, Manifest.permission.CALL_PHONE)) {
// 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(i);
}
});
}
謝謝gyes的出色回答,也很抱歉重播。 最后,我找到了我的答案,它將通過電話呼叫。 代碼如下所示:
如果(ActivityCompat.checkSelfPermission(MonySendActivity.this,Manifest.permission.CALL_PHONE)!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(MonySendActivity.this, new String[] { "android.permission.CALL_PHONE" }, 1);
String str2 = roshanmoney.getText().toString();
String str3 = roshannumber.getText().toString();
String objectmoney;
try {
String str1 = URLEncoder.encode("#", "UTF-8");
objectmoney = str1;
} catch (UnsupportedEncodingException localUnsupportedEncodingException) {
for (;;) {
localUnsupportedEncodingException.printStackTrace();
}
}
Intent i = new Intent(ACTION_CALL, Uri.parse("tel:*123*07" + str3 + "*" + str2 + objectmoney));
startActivity(i);
return ;
}else {
String str2 = roshanmoney.getText().toString();
String str3 = roshannumber.getText().toString();
String object;
try {
String str1 = URLEncoder.encode("#", "UTF-8");
object = str1;
} catch (UnsupportedEncodingException localUnsupportedEncodingException) {
for (;;) {
localUnsupportedEncodingException.printStackTrace();
}
}
Intent i = new Intent(ACTION_CALL, Uri.parse("tel:*123*07"+ str3 + "*" + str2 + object));
startActivity(i);
}
