如何在Android中使用意图打电话?

我正在使用以下代码在Android中拨打电话，但它给了我安全例外，请帮助。

 posted_by = "111-333-222-4";

 String uri = "tel:" + posted_by.trim() ;
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(uri));
 startActivity(intent);

权限

 <uses-permission android:name="android.permission.CALL_PHONE" />

异常

清单中的请求权限

<uses-permission android:name="android.permission.CALL_PHONE" />

调用使用此代码

Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:99xxxxxxxx"));
try {
    startActivity(in);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(mcontext, "Could not find an activity to place the call.", Toast.LENGTH_SHORT).show();
}

一切都很好。

我只是在清单文件中的应用程序标记之前放置了调用权限标记

现在一切都很正常。

使用完整代码

          Intent callIntent = new Intent(Intent.ACTION_DIAL);
          callIntent.setData(Uri.parse("tel:"+Uri.encode(PhoneNum.trim())));
          callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          startActivity(callIntent);

从拨号器调用(不需要权限):

   fun callFromDailer(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_DIAL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

从应用程序直接呼叫(需要权限):

  fun callDirect(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_CALL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: SecurityException) {
            Toast.makeText(mContext, "Need call permission", Toast.LENGTH_LONG).show()
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

许可:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

    final public void Call(View view){

    try {

        EditText editt=(EditText)findViewById(R.id.ed1);
        String str=editt.getText().toString();
        Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:"+str));
        startActivity(intent);
    }
    catch (android.content.ActivityNotFoundException e){

        Toast.makeText(getApplicationContext(),"App failed",Toast.LENGTH_LONG).show();
    }

为了避免这种情况，可以使用GUI来输入权限。Eclipse会考虑在哪里插入权限标记，通常情况下不这样做是正确的
