我想从我的Android应用程序（来自Detail Activity）拨打电话。我正在使用此代码，它没有任何错误，但当我在我的虚拟设备上运行应用程序时，“呼叫”按钮不起作用。 如果有人得到这个，请帮助。
这是我的详细活动类

尝试在
中删除此行android:onClick="onClickCall"
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Call"
android:id="@+id/button"
android:layout_marginBottom="68dp"
android:onClick="onClickCall"
android:layout_alignParentBottom="true"
android:layout_alignRight="@+id/imageView"
android:layout_alignEnd="@+id/imageView" />

尝试这样的事情......
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + number));
try {
startActivity(intent);
} catch (Exception e) {
Toast.makeText(MyActivity.this, "Error", Toast.LENGTH_SHORT).show();
}

解决方案1： 删除android：onClick =＆＃34; onClickCall＆＃34;从你的布局xml按钮
或
解决方案2：
要从xml使用onclick，你应该声明一个没有Listner
的方法public void onClickCall(View v) {
// does something
}
所以你应该删除这个
b.setOnClickListener(
new View.OnClickListener() {
public void onClick(View view) {
String phNum = "tel:" + con;
Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse(phNum));
//myIntent.setData(Uri.parse(phNum));
if (ActivityCompat.checkSelfPermission(DetailActivity.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(myIntent);
}
});
并执行此操作：
public void onClickCall(View v) {
String phNum = "tel:" + con;
Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse(phNum));
//myIntent.setData(Uri.parse(phNum));
if (ActivityCompat.checkSelfPermission(DetailActivity.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(myIntent);}
