【问题描述】：
我已将按钮设置为在单击按钮时会发送呼叫。单击按钮时，应用程序崩溃。请帮我调试一下。请建议是否有其他方法我可以编写一个按钮以在单击它时直接发送呼叫。我也已在设置中授予权限。
package com.example.allegiant;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button dial;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dial = findViewById(R.id.dial);
}
public void onDialButton(View view) {
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tell:12345678"));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return;
}
startActivity(intent);
}
}
这里是日志
